A car is racing around a perfectly circular track at a constant speed. The car makes one complete trip around the track in 100 seconds. The car  decides to move to a different lane whose radius is half as big as the first one, but it still makes one lap in 100 seconds.  What happens to the force keeping the car on the track?  The force does not change The force is twice as big as it was The force is now half of what it was The force is now one-fourth of what it was. The force is now four times what it was

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.
