Question

In uniform circular motion, what is the relationship between centripetal force and the object’s mass?

Options

Choose one · Correct answer highlighted

Explanation

Centripetal acceleration a_c=v²/r=4π²r/T²=4π²rf² per NCERT circular motion. Substituting r and frequency/period gives a_c value matching It is directly proportional. Other options use incorrect r or f, so D is correct.
