This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

For a simple pendulum, why is the centripetal acceleration zero at the apex
Consider the following question.
The answer is $C$.
I am wondering why is there no centripetal force at point R acting towards the center to give it a centripetal acceleration such that the result …
