Considering a system having two masses ...

Considering a system having two masses `m_(1)` and `m_(2)` in which first mass is pushed towards centre of mass by a distance a, the distance required to be moved for second mass to keep centre of mass at same position is :-

A

`(m_(1))/(m_(2))a`

B

`(m_(1)m_(2))/(a)`

C

`(m_(2))/(m_(1))a`

D

`((m_(2)m_(1))/(m_(1) + m_(2)))a`

Text Solution

Verified by Experts

The correct Answer is:
A

`Deltabar(x) = (m_(1).Deltax_(1) + m_(2).Deltax_(2))/(m_(1) + m_(2))`
`rArr 0 = (m_(1)a + m_(2)Deltax_(2))/(m_(1) + m_(2))`
`rArr Deltax_(2) = -(m_(1)a)/(m_(2))`
