Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

If the radius of the path of a body in uniform circular motion is doubled and the speed is kept the same the force needed must be
(A) No answer
B half as great as before.
four times the size as before.
D twice as large as before.
E the same as before.
