The escape velocity for a planet is upsilon_e . A tunnel is dug along a diameter of the planet and a small body is dropped into it at the surface. When the body reaches the centre of the planet , its speed will be

The escape velocity for a planet is upsilon_e . A tunnel is dug along a diameter of the planet and a small body is dropped into it at the surface. If R is the radius of the planet and g is the acceleration due to gravity at its surface then the body will reach the centre of the planet in time

A tunnel is dug along a diameter of the planet. A particle is dropped into it at the surface. The particle reaches the centre of the planet with speed v. If v_(e) is the escape velocity from the surface fo the planet, then-

The escape velocity for a body projected from a planet depends on
