Question

if a particle of mass M is moving in a horizontal circle of radius R with a centripetal force (-k/r2) , total energy is

Answer 1

The centripetal force F acting on a particle moving in circular orbit depends on its mass m, radius of the circle r, and the speed of particle... For a particle moving in a horizontal circle, what is the direction of friction? A particle moves along a circle of radius R with constant angular speed.
