Question

If the kinetic energy of a particle moving with a constant speed on a circular path of radius 5 m is 100 j, then force is

Answer 1

Answer:

the force is 3.18 N. (approx.)

Explanation:

the length of circular path=(2*22*5)/7 m

the work done = 100J

so, force = (100*7)/(2*22*5)N

=3.18N (approx.)
