A body is tied up a string of length l and rotated in vertical circle at minimum speed. When it reaches at highest point string breaks and body moves on a parabolic path in presence of gravity according to fig. in the plane of point A, value of horizontal range AC will be

A

`x = l`

B

`x = 2l`

C

`x = sqrt(2l)`

D

`x = 2sqrt(2l)`

Text Solution

Verified by Experts

The correct Answer is:
B

`V_(B) = sqrt(gl)`
`x = V_(B) sqrt((2 xx 2l)/(g)) = x = 2l`.
