The mass of the Moon is 0.0123 times that of the Earth and the separation between their centers is `3.83 xx 10^8` m. Determine the location of their center of mass relative to the center of the Earth:

The mass of the earth is 81 times the mass of the Moon and the distance between the earth and the Moon is 60 time the, radius of the earth. If R is the radius of the earth, then the distance between the Moon and the point on the in joining the Moon and the earth where the gravitational force becomes zero is

Solve the following examples/numerical problems : If the mass of a planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the ratio of the escape velocity on the earth to the escape velocity on the planet?

Solve the following examples / numerical problems: The mass of a planet is 3 times the mass of the earth. Its diameter is 25600 km and the earth's diameter is 12800km. Find the acceleration due to gravity at the surface of the planet. [g (earth)=9.8 m/s^2]

The moon's radius is 1//4 that of the earth and its mass 1//80 times that of the earth. If g represents the acceleration due to gravity on the surface of the earth, that on the surface of the moon is

If mass of planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet?

The center of mass of a system of two particles divides the distance between them.

Solve the following examples/numerical problems : If the mass of a planet is 8 times that of the earth and its radius is twice the radius of the earth , what will be the escape velocity for that planet?( Escape velocity for the earth=11.2 km/s)

The mass of a planet is 6 times the mass of earth and its radius is 3 times that of the earth . Considering acceleration due to gravity on earth to be 9.8m//s^2 , calculate the value of g on the other planet.

If mass of a body is M on the earth surface, then the mass of the same body on the moon surface is

Solve the following examples / numerical problems: The mass of a planet is four times that of the earth and its radius is double the radius of the earth. The escape velocity of a body from the earth is 11.2xx10^3 m/s. Find the escape velocity of a body from the planet.
