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

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 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 body is dropped from a height equal to radius of the earth. The velocity acquired by it before touching the ground is

Statement-1 : A body released from a height equal to the radius (R ) of the earth. The velocity of the body when it strikes the surface of the earth will be sqrt(2 g R) . Statement -2 : As upsilon^(2) = u^(2) + 2 as.

A body attains a height equal to the radius of the earth. The velocity of the body with which it was projected is

A body of mass m is placed on the earth's surface . It is taken from the earth's surface to a height h = 3 R where R is the radius of the earth. The change in gravitational potential energy of the body is
