A particle of mass m moves along a circular path of radius r with a centripetal acceleration `a_(n)` changing with time t as `a_(n)=kt^(2)`, where k is a positive constant. The average power developed by all the forces acting on the particle during the first `t_(0)` seconds is

Options

A. at any time 't' force acting on particle is `msqrt(kr+ K^(2)t^(4))`
B. power developed at any time t is mkrt
C. Power developed at any time t is `mk^(3//2)//r^(3//2)t`
D. Tangential acceleration is also varying,

Answer

A, B
