A stone is dropped from a height equal to `nR`, where `R` is the radius of the earth, from the surface of the earth. The velocity of the stone on reaching the surface of the earth is

A stone is dropped from a height equal to 3R , above the surface of earth. The velocity of stone on reaching the earth's surface is

A body is released from a height 5R where R is the radius of the earth. Then that body reaches the ground with a velocity equal to

If R is radius of the earth, the height above the surface of the earth where the weight of a body is 36% less than its weight on the surface of the earth is

An earth satellite of mass m revolves in a circular orbit at a height h from the surface of the earth. R is the radius of the earth and g is acceleration due to gravity at the surface of the earth. The velocity of the satellite in the orbit is given by

The escape velocity from the surface of the earth is (where R_(E) is the radius of the earth )

A geostationary satellite is orbiting the earth at a height of 6R above the surface of the earth, where R is the radius of the earth. The time period of another satellite at a height of 2.5 R from the surface of the earth is …… hours.

A particle is throws vertically upwards from the surface of earth and it reaches to a maximum height equal to the radius of earth. The radio of the velocity of projection to the escape velocity on the surface of earth is

A ball is thrown vertically upwards with a velocity equal to half the escape velocity from the surface of the earth. The ball rises to a height h above the surface of the earth. If the radius of the earth is R, then the ratio h/R is
