    A plane mirror may form a virtual as well as real image.
    A plane mirror may form a real image, when the pencil of light incident on the mirror is convergent. Children, during their play form an image of sun as wall by a strip of plane mirror.

    The force experienced by a unit positive charge placed at a point is termed as the electric field intensity at that point.
    It is vector quantity and it’s direction is in the direction of force acting on +ve test charge.
    The SI unit of electric field intensity is NC-1.

    What aman said is true. If it is numerical for 1m we need to spend so much time for each question. 20 marks r there at least 15 numerical will be there so at least 30 min we need to total to spend on it. We need to maintain our speed to solve the mcq questions.

    Consider a series of dots "........." When we look closely,we can differentiate between the different constituent dots. but when we go far apart, they appear as a single line and it would not make a big difference if a few dots are removed or aadded. in the same way,charges a very small entities and in the microscopic level, the addition and removal of few charges would make a huge difference, while in the macroscopic level, just like the dots appearing to be a single line, charge appears to be continuous and the addition or removal of  a few charges wouldn't make any noticeable difference. This is the meaning of grainy nature and how it appears to be continuous...
