A particle of mass `m` describes a circular path of radius 'r' such that speed `V = alpha sqrt(S)` (S is distance traveled). Then power is proportional to :

A particle of mass m describes a circular path of radius 'r' such that speed V = alphasqrt(S) (S is distance traveled). Then power is proportional to:

A particle of mass 'm' describes circular path of radius 'r' such that its kinetic energy is given by K = "as"^(2) . 's' is the distance travelled, 'a' is constant :

A particle of mass M moves in a circular path of radius r with a constant speed equal to V. Then its centripetal acceleration is

A particle of mass M is moving in a circular path of radius 2m. Its speed depends on the distance covered by the particle from the hegining according to the relation c = ks, where k is a positive constant and s is the distance covered. The power of force acting on teh particle when the particle has covered half of the circular path will be :

A particle of mass 'm' is moving on a circular path of radius 'r' with uniform speed 'v'. Rate of change of linear momentum is
