In the previous problem , if a bomb explodes into three parts of mass ratio `1 : 1 : 2` , one smaller part retraces its path, the second smaller part coming to rest, the distance from the point of projection , where the heavier part strikes the ground is

A

`75 m`

B

`95 m`

C

`105 m`

D

`120 m`

Text Solution

Verified by Experts

The correct Answer is:
C
`x_(c.m.) = R = (m xx 0 + m xx (R )/(2) + 2m x_(0))/(4m)`
`4 R = (R )/(2) + 2 x_(0) rArr x_(0) = ( 7 R)/(4) = ( 7 xx 60)/(4) = 105 m`
