Question

For a particle inside a uniform spherical shell, the gravitational force on the particle is (A) infinite (B) zero (C) (-G m1 m2/r2) (D) ( Gm 1 m 2/ r 2)

Tardigrade Admin · Accepted Answer

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.

zero

$\frac{- G m _{1} m _{2}}{r ^{2}}$

$\frac{G m _{1} m _{2}}{r ^{2}}$

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.
