Given:

Mass of body = m Kg

Radius of vertical circle = R m

From the free body diagram of body at lowest point, we can write, According Newton’s 2nd law of motion,

Fnet = mg-T

Fnet = mv12/R (Centrifugal force)

mg-T = mv12/R …(1)

Where,

v1 = Velocity at lowest point.

m = mass of body

T = tension in string

From the free body diagram of body at highest point , we can write, Fnet = T + mg

Fnet = mv22/ R

Where,

v2 = velocity of body at highest point,

T + mg = mv22/ R …(2)

From equation (1) and (2) we conclude that option (1) is correct.
