Question

A particle of mass m is tied to a light string and rotated with a speed v along a circular path of radius r. If T = tension in the string and mg = gravitational force on the particle then the actual forces acting on the particle are :

G1 Physics · Accepted Answer

Centripetal force is not an additional force; it is the radial resultant of actual forces. The only actual forces are tension T and weight mg. Hence A.
