1.	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
Answer» at any TIME 't' force ACTING on particle is `msqrt(kr+ K^(2)t^(4))` power developed at any time t is mkrt Power developed at any time t is `MK^(3//2)//r^(3//2)t` TANGENTIAL acceleration is also varying, Answer :A::B
