Question

what is the force of attraction due to hollow spherical shell of uniform density on a
point mass
a. when it is situated outside the shell and
b. When it is situated inside the shell.
​

Answer 1

Answer:

The gravitational force on an object within a hollow spherical shell is zero. The gravitational force on an object within a uniform spherical mass is linearly proportional to its distance from the sphere's center of mass
