Answer #1

Information provided-A body having mass M is moving in a circular path of radius(string length) L.

concept to be used- Equilibrium

To keep the mass parallel to the ground ,there should not be any vertical motion and it should move with a constant speed.

As the body is moving in a circular pathe, centripetal force is necessary which is provided by the tension in the string.

so the body remains in equilibrium due to the combined effect of tension and centrifugal force.
