A particle is moving on a circular arc AB as shown in figure. The centripetal force acting on the particle is found to be 
/3 N. Then –
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, c): Duration of motion = 
< F > = 
= 
= 1N
Centripetal force is always perpendicular to velocity. Hence power delivered by this force is zero.
