In the figure given below, two particles of masses m and 2m are fixed in place on an axis. Where on the axis can a third particle of mass 3m be placed (other than at infinity) so that the gravitational force on it from the first two particles is zero?

A

Between m and 2 m

B

Left of m

C

Right of 2m

D

The net gravitational force on 3m never be zero

Text Solution

Verified by Experts

The correct Answer is:
`A:B`
To the left on m and right of 2m, the force on 3m due to both particles will be in same direction so net force can’t be zero.
