Question

a particlr of mass m moves with constant speed v on a circular path with radius r . find magnitude of average force in half revolution​

Answer 1

_____________________

The force acting on the particle are centripetal force, normal force and the force of gravity. Normal force and the force of gravity cancel each other and the only unbalanced g = force is centripetal force which is equal to :

Fc = mv²/r

where v is speed and r is radius.
