Physical Science 1.11: 3.1.3 Noncontact Forces

Repel

Attract

Connect one charge to the other

Bend away from both charges

If both charges are doubled, the electric force doubles.

If both charges are doubled, the electric force increases by a factor of 4.

If one charge is doubled, the electric force is divided in half.

If one charge is doubled, the electric force doubles.

If the distance between the charges is divided by 2, the electric force is also divided by 2.

If the distance between the charges is divided by 2, the electric force remains the same.

If the distance between the charges is divided by 2, the electric force doubles.

If the distance between the charges is divided by 2, the electric force more than doubles.
