A body of mass `m` is moving along a circular path of radius `R` such that its kinetic energy at any instant is `k=k_(0)((t)/(t_(0)))^(2)`
where `t_(0)` is an appropriate constant. Then

Options

A. The magnitude of tangential component of force acting on it must be constant.
B. The magnitude of centripetal force acting on the body will be directly proportional to `t^(2)`.
C. After a long time, the resultant force will make a very small angle with the radius.
D. The magnitude of centripetal force acting on the body will be directly proportional to `t`.

Explanation

Use `F_(t)=m(dv)/(dt)` and `F_(t)=(mv^(2))/(r )`
