Answer 1

ANSWER

zero

SOLUTION

The forces from all the parts of the shell will cancel each other at any point inside the shell. therefore net force will be zero

 Use Gauss's Law  directly, then you can simply think about it this way.

In the exact  middle of the hollow shell, there will be a gravitational pull from  every point on the shell, but each point will have a different  direction.

In fact, for every point with a gravitational pull in one  direction, there is a point on the exact opposite side of the ball with  the same amount of pull but in the opposite direction.
