Question

A particle with constant angular velocity in circular path of certain radius and is acted upon by a certain centripetal force f. If centripetal force is kept constant and angular velocity is doubled . Determine the new radius of the path

Answer 1

R = r/4

Explanation:

mw^2 × r = m (2w)^2 R

w^2 × r = 4w^2 R

R = r/4
