With what minimum speed should m be projected from point P in presence of two fixed spherical masses M each at $A$ and $B$ is shown in figure such that mass $m$ should escape the gravitational attraction of $A$ and $B$ .

Options:

Answer:

Solution:

Total mechanical energy $= 0$

$- 2 \frac{GM}{a} m + \frac{1}{2} m v_{e}^{2} = 0 v_{e} = 2 \frac{GM}{a}$
