Question

1) A body is in U.C.M of radius r. The centrifugal force acting on the body is, F The kinetic energy
of the body is

​

Answer 1

Answer:

Kinetic energy of the particle is 0.5 Fr

Explanation:

As we know that centrifugal force is given as

$F = \frac{mv^2}{r}$

here we know that radius of the circle is "r"

so we can say that

$mv^2 = Fr$

now the kinetic energy of the body is given as

$KE = \frac{1}{2}mv^2$

so we have

$KE = \frac{1}{2}Fr$
