Question

Intensity of gravitational field inside a hollow uniform spherical shell

• A. is zero at centre but non-zero at other points.
• B. is non-zero at all points.
• C. is zero at all points because various region of shell attracts point mass in various directions, these forces cancel each other completely.
• D. is non-uniform & varies linearly.

Answer 1

The correct option is C is zero at all points because various region of shell attracts point mass in various directions, these forces cancel each other completely.

Gravitational field intensity, $\overrightarrow{g}=0$ inside all points of uniform spherical shell because of given reason in option. It is known as the Shell Theorem.
