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

An object moves around a circle. If the radius is doubled keeping the speed the same then the
magnitude of the centripetal force must be:
none of the given choices
O four times as great
O half as great
O the same
Otwice as great
