Two lead balls of mass m and 2 m are placed at a separation d. A third ball of mass m is placed at an unknown location on the line joining the first two balls such that the net gravitational force experienced by the first ball is `(6Gm^(2))/(d^(2)` . What is the location of the third ball?

Text Solution

Verified by Experts

The correct Answer is:
Exactly midway between the two balls OR at a dietance of `(d)/(2sqrt(2))` form the ball of mass m
