The masses and radii of the earth and the moon are `M_1,R_1 and M_2,R_2` respectively. Their centres are at a distance d apart. Find the minimum speed with which a particle of mass m should be projected from a point midway between the two centres so that it escape to infinity.

Text Solution

Verified by Experts

The correct Answer is:
`sqrt((4G)/d(M_1-M_2))`
