Answer :

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


R = radius of path


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.
