Question

In uniform circular motion, what is the role of the centripetal acceleration?

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 changes the direction of velocity. Other options use incorrect r or f, so C is correct.
