Question: An initially uncharged hollow metallic sphere with radius of 5 cm has a small object with a charge of +10 mC carefully placed at the center of the sphere through a hole in the latter's surface.

Part A: With the charge in place, what charge is now present on the outside surface of the sphere?

I know the answer but don't understand how to get there. Please show all work and steps. Thanks.
