An object is released from a height twice the radius of the earth on the surface of earth. Find the speed with which it will collide with group by neglecting effect of air. (Take, R radius of earth and mass of earth as M)

An object is dropped from height h=2 R on the surface of earth. Find the speed with which it will collide with ground by neglecting effect of air. (Where R is radius of earth, take mass of earth M)

An object is dropped from height h=2 R on the surface of earth. Find the speed with which it will collide with ground by neglecting effect of air. (Where R is radius of earth, take mass of earth M)

An object is projected in upward direction with speed sqrt((gR)/6) from height h= 2R above the surface of earth. The speed with which the object will collide the earth surface. (Neglect the air drag, R us the radius of the earth and M is mass of earth

A man weighs 'W' on the surface of the earth and his weight at a height 'R' from surface of the earth is ( R is Radius of the earth )

A man weighs 'W' on the surface of the earth and his weight at a height 'R' from surface of the earth is ( R is Radius of the earth )

The work done to raise a mass m from the surface of the earth to a height h, which is equal to the radius of the earth, is :
