An object of mass 20 kg is raised to a height of 50 m from the surface. Find its potential energy...

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy ? If the object is allowed to fall, find its kinetic energy when it is half - way down.

A particle of mass 'm' is raised to a height h = R from the surface of earth. Find increase in potential energy. R = radius of earth. g = acceleration due to gravity on the surface of earth.

A body of mass 4kg, is taken from a height of 5 m to a hegiht 10m. Find increase in potential energy.

A body of mass 10 kg is dropped from a height of 20 m. (Take g = 10 m/s^2) Fuid its potential energy before it is dropped

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)

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

An object of mass 8 kg is placed at a height of 5 m above the ground. What kind of energy does this object possess?

An object of mass 12 kg is at a certain height above the gorund if the potential energy of the object is 480J find the height at which the object is withj respect to the ground Given, g = 10m//s^2

A body of mass of 20 kg is at rest on the earth's surface. (i) Find its gravitational potential energy. (ii) Find the kinetic energy to be provided to the body to make it free from the gravitational influenece of the earth. (g=9.8m//s^(2), R=6400km)
