In what ways are electrical force similar to AND different from gravitational force?
Similar: both are field forces
Different: Electrical forces can attract or repel; gravitational force only attracts

Suppose two charged particles exert a force of 20N on each other when separated by a distance of 5cm. How much force will they exhibit upon each other if their distance is increased to 10cm?
5N; force is decreased by factor of four

Two charges q1 and q2, when separated by a distance of 10cm, exert a force of 100N on each other. If the charge on each object doubles, and the distance between them is quadrupled, what is the net charge acting on each particle?
25N

Explain why an object placed within a sphere made of conductive material carrying electrons on its surface will not experience an electrical force acting upon it.
Electrons will be uniformly repulsed across the surface of the sphere, causing their electrical forces to effectively cancel for anything placed inside the sphere.

What is the net charge of a charged capacitor?
Zero. When the plates on a capacitor achieve equal and opposite charge, they effectively cancel.
