The mass of the Earth is 6.0xx10^(24) kg. The potential energy of a body of mass 50 kg at a distance of 6.3xx10^(9) m from the centre of the Earth is:

The mass of the earth is 6 xx 10^(24) kg . The constant of gravitation G = 6.67 xx 10^(-11) "N-m"^(-2) kg^(-2) . The potential energy of the earth and moon system is -7.79 xx 10^(28) J . Determine the mean distance between earth and moon.

The mass of the earth is 6.0 xx 10^(24) kg and its radius is 6.4 xx 10^(6) m . How much work will be done in taking a 10 kg body from the surface of the Earth to infinity ? What will be the gravitational potential energy of the body on the Earth's surafce ? G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

The mass of the earth is 6 × 10^(24) kg and that of the moon is 7.4 xx 10^(22) kg. If the distance between the earth and the moon is 3.84xx10^(5) km, calculate the force exerted by the earth on the moon. (Take G = 6.7 xx 10^(–11) N m^(2) kg^(-2) )
