What are the Characteristics of electrostatic force

Yogita Ingle 7 years, 4 months ago

If the two charges have the same sign, the electrostatic force between them is repulsive
If they have different sign, the force between them is attractive.
An electric field is a vector field that associates to each point in space the Coulomb force experienced by a test charge.
Coulomb force is also called electrostatic force.It is the force exerted due to repulsion of similar charges.

What is centripetal acceleration

Posted by Vishali Ramamurthy 7 years, 4 months ago

CBSE > Class 12 > Physics

2 answers

Yogita Ingle 7 years, 4 months ago

Centripetal acceleration is the rate of change of tangential velocity. Centripetal force is the net force causing the centripetal acceleration of an object in circular motion. The derivation of centripetal acceleration is very important for students who want to learn the concept in-depth. The direction of centripetal force is towards the center which is perpendicular to the velocity of the body.

A photosensitive surface emits photoelectron when red light falls on it. Will the surface emit photelectron when blue light is incident on it? Give reason

Posted by Swati Raghav 7 years, 4 months ago

CBSE > Class 12 > Physics

Peeyush Kumar Jain 7 years, 4 months ago

Off-course because E=hv ,where v=frequency of incident light ,frequency of blue light is greater then that of red light so surface will definitely emit photoelectrons.
