The radius of the earth`R` and acceleration due to gravity at its surface is `g`. If a body of mass `m` is sent to a height of `R//4` from the earth's surface, the potential energy increases by

The earth’s radius is R and acceleration due to gravity as its surface is g. If a body of mass m is sent to a height of R/5 from the earth’s surface the PE increase (h = R/5) by:

The radius and mass of Earth are R and M . The acceleration due to gravity at its surface is g . Calculate the work required in raising a body of mass m to a height h from the surface of earth.

Obtain an expression for the acceleration due to gravity on the surface of the earth in terms of mass of the earth and its radius. Discuss the variation of acceleration due to gravity with altitude and depth. If a body is taken to a height R / 4 from the surface of the earth, find percentage decrease in the weight of the body ? Here R is the radius of the earth.

If R is the radius of earth and g is acceleration due to gravity on the surface of the earth, then binding energy of the satellite of mass m at the height h above earth's surface is · (r is orbital radius of satellite)

If a body of mass m is raised to height 2 R from the earth s surface, then the change in potential energy of the body is (R is the radius of earth)

If a body of mass m is raised to height 2 R from the earth s surface, then the change in potential energy of the body is (R is the radius of earth)
