Question
Two bodies, each of mass M, are kept fixed with a separation 2L. A particle of mass m is projectedfrom the midpoint of the line joining their centres, perpendicular to the line. The gravitational constantis G. The correct statement(s) is (are) :-
Options
A.The minimum initial velocity of the mass m to escape the gravitational field of the two bodiesis 
B.The minimum initial velocity of the mass m to escape the gravitational field of the two bodies is 
C.The minimum initial velocity of the mass m to escape the gravitational field of the two bodies is 
D.The energy of the mass m remains constan
Solution
Total energy of m is conserved for escape velocity
K.Ef + P.Ef = K.Ei + P.Ei
