Question

a particle is revolving in circle of radius r and centre O with uniform angular velocity w(omega)

Answer 1

At the point when a body is spinning around a circular way, it encounters 2 forces: Centrifugal force and Centripetal Force.

Centrifugal force(Latin for "center fleeing") portrays the inclination of a protest following a curved way to fly outwards, far from the focal point of the curve. It's not by any stretch of the imagination a force; it comes about because of inactivity — the inclination of an object oppose any adjustment in its condition of rest or motion.

Centripetal force is a genuine force that balances the radiating power and keeps the object from "flying out," keeping it moving rather with a uniform speed along a circular path.

Centripetal force: Fc = mv2/r = mw2r

Along these lines acceleration of a molecule, the outspread way is equivalent to w2r where w is the velocity of molecule and r is the radius of the circular path.
