PrevPreviousThe mass of the earth is 6.00 × 10^24 kg and that of the moon is 7.40 × 10^22 kg . The constant of gravitation G=6.67 × 10^-11 N-M^2/kg^2. The potential energy of the system is -7.79 × 10^28 joules . The mean distance between the earth and moon is

NextThe masses and radii of the earth and moon are M1,R1 and M2,R2 respectively. Their centres are distance d apart. The minimum velocity with which a particle of mass m should be projected from a point midway between their centres so that it escapes to infinity isNext
