CBSE will ask two Case Study Questions in the CBSE class 12 Physics questions paper. Question numbers 15 and 16 are case-based questions where 5 MCQs will be asked based on a paragraph. Each theme will have five questions and students will have a choice to attempt any four of them. You can download CBSE Class 12 Physics case study questions from the myCBSEguide App and our free student dashboard.

Case Study Questions

You can Score High

CBSE class 12 Physics question paper will carry questions for 70 marks. Certainly, the question paper is a bit easier this year. It is because the syllabus is already reduced and there are more internal choices. Besides this, the case study questions are a plus to winning the game with good marks.

In simple words, all circumstances are in favour of the sincere students who are working hard to score high this year. Although it has been a difficult time for students as they were not getting the personal attention of the teachers. We know that online classes have their own limits, but we still expect better scores, especially from students who are putting extra effort into their studies.

Class 12 Physics Case Study Questions

CBSE class 12 Physics question paper will have case study questions too. These case-based questions will be objective type in nature. So, class 12 Physics students must prepare themselves for such questions. First of all, you should study NCERT Textbooks line by line and then you should practice as many questions as possible.

Case Study Syllabus

We know that CBSE has reduced the syllabus. Hence, practice only relevant questions. don’t waste time on case study questions from deleted portion. It is of no use. You can download the latest class 12 Physics case study questions from the myCBSEguide App.

Physics Case Studies

Class 12 Physics has many chapters but all chapters are not important for case studies. As we know case studies are not exactly given from NCERT books but these may be extracted from some newspaper articles, magazines, journals or other books. So, it is very much important that you are studying only the most relevant case studies. Here, the myCBSEguide app helps you a lot. We have case study questions that are prepared by a team of expert teachers. These experts exactly know what types of questions can come in exams.

Case Study Questions

There are a number of study apps available over the internet. But if you are a CBSE student and willing to get an app for the CBSE curriculum, you have very limited options. And if you want an app that is specifically designed for CBSE students, your search will definitely end on finding myCBSEguide. Case study questions are the latest updates in CBSE syllabus. It is exclusively available in the myCBSEguide app.

12 Physics Case Study Questions

Here are some example questions. For more questions, you can download the myCBSEguide App.

Physics Case Study -1

Read  the following source and answer any four out of the following questions:
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of charges positive and negative charges. Also, like charges repel each other whereas unlike charges attract each other.

  1. Charge on a body that carries 200 excess electrons is:
    1. -3.2 ×× 10-18 C
    2. 3.2 ×× 10 18 C
    3. -3.2 ×× 10-17 C
    4. 3.2 ×× 10 -17  C
  2. Charge on a body that carries 10 excess electrons is:
    1. -1.6 ×× 10-18 C
    2. 1.6 ×× 10 -18 C
    3. 2.6 ×× 10-18 C
    4. 1.6 ×× 10-21 C
  3. Mass of electron is:
    1. 9.1 ×× 10-31 kg
    2. 9.1 ×× 10-31 g
    3. 1.6 ×× 10-19 kg
    4. 1.6 ×× 10-19 g
  4. A body is positively charged, it implies that:
    1. there is only a positive charge in the body
    2. there is positive as well as negative charge in the body but the positive charge is more than the negative charge
    3. there is equally positive and negative charge in the body but the positive charge lies in the outer regions
    4. the negative charge is displaced from its position
  5. On rubbing, when one body gets positively charged and the other negatively charged, the electrons transferred from the positively charged body to the negatively charged body are:
    1. valence electrons only
    2. electrons of inner shells
    3. both valence electrons and electrons of the inner shell.
    4. none of the above

Physics Case Study -2

Read the following source and answer any four out of the following questions:
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms. Also, Resistivity is the electrical resistance of a conductor of unit cross-sectional area, and unit length. … A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents.

  1. Resistivity is independent of:
    1. nature of material
    2. temperature
    3. dimensions of material
    4. none of the above
  2. As compared to short wires, long wires have _______ resistance.
    1. more
    2. less
    3. same
    4. zero
  3. As compared to thin wires, thick wires have _______ resistance.
    1. more
    2. less
    3. same

Physics Case Study -3

Read the source given below and answer any four out of the following questions:
The Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom. Rutherford’s model introduced the nuclear model of an atom, in which he explained that a nucleus (positively charged) is surrounded by negatively charged electrons.

  1. Which of the following statements does not form a part of Bohr’s model of a hydrogen atom?
    1. The energy of the electrons in the orbit is quantized
    2. The electron in the orbit nearest the nucleus has the lowest energy

  3. When an electron jumps from its orbit to another orbit, energy is:
    1. emitted only
    2. absorbed only
    3. both (a) and (b)
    4. none of these
  4.  What were the limitations of the Rutherford model which could not explain the observed features of atomic spectra explained in Bohr’s model of a hydrogen atom?
    1.  It must emit a continuous spectrum
    2.  It loses its energy
    3. Gaining its energy
    4. A discrete spectrum
  5. When an electron remains between orbits its momentum is:
    1. quantized
