Question

what is the formula of centrifugal force​

Answer 1

This apparent outward force is described by Newton's Laws of Motion.  

The radius (r) of this circle is equal to the mass (m) times the square of the velocity (v) divided by the centripetal force (F), or r = mv^2/F. The force can be calculated by simply rearranging the equation, F= mv^2/r

Answer 2

The radius (r) of this circle is equal to the mass (m) times the square of the velocity (v) divided by the centripetal force (F), or r = mv^2/F.
