What .will be the increase in potential energy if an object of 100 kg is taken.at a height of 6400 km from the earth’s surface, `[g = 9.8 m//s^2, R =6400 km]`

Calculate the value of ‘g' at height ‘h' from the earth’s surface.

What will be the kinetic energy , potential energy and total energy of an artificial satellite of mass 10^5 kg situated at a height of 3400 km above the surface of the earth ? [g=9.8 m*s^(-2) , radius of the earth=6400 km]

What will be the gain in the potential energy of an object of mass m raised from the surface of the earth to a height equal to the radius R of the earth ?

The acceleration due to gravity at a height R ( radius of the earth ) from the earth' s surface is

If g is the acceleration due to gravity on the surface of the earth , the gain in potential energy of an object of mass m raised from the earth's surface to a height equal to the radius R of the earth is

How much energy would be needed for a body of mass 10 kg to escape from the earth ? Take g= 10 m*s^(-2) and R_e=6400 km.

Calculate the kinetic energy , potential energy and total energy of a geostationary satellite of mass 100 tonne. The radius of the earth is 6400 km and the radius of the orbit of the satellite is 42400 km.

What is the condition for setting up an artificial satellite at a height h from the earth’s surface? (Radius of the earth = R, mass of the earth= M).

The change in the gravitational potential energy when a body of mass m is raised to a height nR above the surface of the earth is (here R is the radius of the earth)
