In case of a projectite , speed of the particle at the top most position is half of its initial speed . The angle of projection with horizontal plane is

A

`30 ^(@)`

B

`45 ^(@)`

C

`60 ^(@)`

D

`tan ^(-1) ((1)/(2))`

Text Solution

Verified by Experts

For the equilibrium of the system , balancing forces in the horizontal direction ,
` T_(1) cos 60 ^(@ ) T_(2) " or " , (T_(1) ) /(T_(2)) = (1)/( 1//2) =(2)/(1) `
