Question
Masses and radii of Earth and Moon are M1, M2 and R1, R2 respectively. The distance between their centre is ′d′. The minimum velocity given to mass ′M′ from the mid point of line joining their centre so that it will escape : -
Options
A.
B.
C.
D.
Solution
Total energy of mass M will become zero,it will be escape
K + U = 0
= 0
(M1 + M2)V =
