Gravitational Field Due To Spheres

Gravitational field due to a solid sphere

Electric field due to spheres

Assertion : Two spherical shells have masses m_(1) and m_(2) . Their radii are r_(1) and r_(2) . Let r be the distance of a point from centre. Then gravitational field strength and gravitational potential both are equal to zero for O lt r lt r_(1) Reason : In the region r_(1) lt r lt r_(2) , gravitational field strength due to m_(2) is zero. But gravitational potential due to m_(2) is constant (but non-zero).

At some point the gravitational potential and also the gravitational field due to earth is zero. The point is
