Answer:
Centripetal force doubles
Explanation:
Since centripetal force is given by
Where F is the centripetal force, m is the mass, v is the centripetal velocity and r is circle radius.
When the radius is reduced to half then the centripetal force will be
Evidently, the centripetal force is doubled compared to the initial.
Note that while the question gives letter v for radius, I used v for velocity and r for radius since these are the standard letters for abbreviating formula of centripetal force.
