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 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

The escape velocity for a planet is v_(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

Suppose a tunnel is dug along a diameter of the earth. A particle is dropped from a point a distance h directly above the tunnel. The motion of the particle as seen from the earth is

Suppose a tunnel is dug along a diameter of the earth. A particle is dropped from a point at a distance h directly above the tunnel. The motion of the particle as seen from the earth is
