Question

How centripetal force produced in uniform circular motion??

Answer 1

The force basically relates to Newton's second. When a force is applied to an object, the force changes the object's velocity's magnitude if it is in the same direction to that of of the motion. When an object rotates in a uniform circular motion it experiences a force that is radially inward. The force is referred to centripetal expressed as

$F=\frac {mv^2}{r}$ where v is velocity, m, is the mass and r is the radius of the circle.
