A particle of mass 
is moving in a circular path of constant radius 
such that its centripetal acceleration 
is varying with time t as, 
, The power delivered to the particle by the forces acting on it is
A
B
C
D
Zero
Text Solution
Verified by ExpertsThe correct answer is:
B
Here the tangential acceleration also exits which requires power.
Given that 
and 
\ \ 
or 
or 
Tangential acceleration 
Now force 
So power
