Question: A particle of mass m is moving in a circular path of constant radius r such that its centripetal acceleration is varying with time t as where k is a constant. The power delivered to the particles by the force acting on it is
Options:
A)
B)
C)
D) zero
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The centripetal acceleration
So, tangential acceleration,
Work is done by tangential force. Power
