A body of mass m rises to a height h = R/5 from the earth's surface where R is earth's radius. If g is acceleration due to gravity , the increase in PE is

Q.

A body of mass m rises to height $h=\frac{R}{5}$ from the earth's surface, where R is earth's radius. If g is acceleration due to gravity at earth's surface, the increase in potential energy is

Q. The earth's radius is R and acceleration due to gravity at its surface is g. If a body of mass m is sent to a height $h=\frac{R}{5}$ from the earth's surface, the potential energy increases by

Q. Gravitational potential of the body of mass m at a height h from surface of earth of radius R is (Take $g=$ acceleration due to gravity at earth's surface)
