What are the Characteristics of electrostatic force

Yogita Ingle 7 years, 1 month 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, 1 month ago

CBSE > Class 12 > Physics

2 answers

Yogita Ingle 7 years, 1 month 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.

Posted by Swati Raghav 7 years, 1 month ago

Peeyush Kumar Jain 7 years, 1 month 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.
