For a particle inside a uniform spherical shell, the gravitational force on the particle is
A.
infinite
B.
zero
C.
$$\frac{{ - G{m_1}{m_2}}}{{{r^2}}}$$
D.
$$\frac{{G{m_1}{m_2}}}{{{r^2}}}$$
Answer :
zero
Solution :
Various regions of spherical shell attract the point mass inside it in various directions. These forces cancel each other completely. Therefore the gravitational force on the particle is zero.
