PhysicsMedium159×since 2002Q7200The masses and radii of the earth and moon are (M₁, R₁) and (M₂, R₂) respectively. Their centres are at a distance 'r' apart. Find the minimum escape velocity for a particle of mass 'm' to be projected from the middle of these two masses :AV=124G(M1+M2)rV = {1 \over 2}\sqrt {{{4G({M_1} + {M_2})} \over r}}V=21r4G(M1+M2)BV=4G(M1+M2)rV = \sqrt {{{4G({M_1} + {M_2})} \over r}}V=r4G(M1+M2)CV=122G(M1+M2)rV = {1 \over 2}\sqrt {{{2G({M_1} + {M_2})} \over r}}V=21r2G(M1+M2)DV=2G(M1+M2)rV = {{\sqrt {2G} ({M_1} + {M_2})} \over r}V=r2G(M1+M2)Check answerSkip
