Answer:
The centripetal force is equal to
In our article on centripetal acceleration, we learned that any object traveling along a circular path of radius r with velocity v experiences an acceleration directed toward the center of its path, a = v 2 r a = \frac{v^2}{r} a=rv2a, equals, start fraction, v, squared, divided by, r, end fraction.
Explanation:
hope this helps :)
