1. A particle of mass m is tied to a light string and rotated | JEE NEET By AIR 89™

1. 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
(a) mg and T only
(b) mg, T and an additional force of mv^2/r directed inwards
(c) mg, T and an additional force of mv^2/r directed outwards
(d) only a force mv^2/r directed outwards
