For a particle inside a uniform spherical shell, the gravitational force on the particle is

Options

Ainfinite
Bzero
C $\frac{-G m_1 m_2}{r^2}$
D $\frac{\mathrm{Gm}_1 \mathrm{ m}_2}{\mathrm{r}^2}$

Correct answer

B. zero

Step-by-step 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.
