Question
A body of mass m is situated at distance 4Re above the Earth′s surface, where Re is the radius of Earth how much minimum energy be given to the body so that it may escape : -
Options
A.mgRe
B.2mgRe
C.
D.
Solution
To escape from the earth total energy of the body should be zero KE + PE = 0
= 0 ⇒ KEmin =
= 0 ⇒ KEmin = Create a free account to view solution
