A body is thrown with a velocity of 9.8 m/s making an angle of `30^(@)` with the horizontal. It will hit the ground after a time

Text Solution

Verified by Experts

The correct Answer is:
3
`M_(B)g(sqrt(2)R - R)-M_(A)g(R- (Rsqrt(3))/(2)) = 0`
`rArr (M_(A))/(M_(B)) = (sqrt(2) - 1)/(1 - (sqrt(3))/(2)) = (0.41)/(1-0.86) = (0.41)/(0.14) = 3`
