If the earth were made of wood, the mass of wooden earth is 10% as much as it is now without the change in its diameter. Calculate the escape velocity of space shot from the surface of wooden earth.
Radius of earth : R = 6400 Km.
Mass of earth : M = 6X 1024 Kg.
Constant of gravitation : G = 6.67 X 10 – 11 Nm2/Kg2
