Electric Force and Coulomb's Law

The electrical interaction between the nucleus and the orbital electron is a force of (attraction) or (repulsion).

• attraction

• repulsion

According to Coulomb's law, if the charge of either the nucleus or the orbital electron were greater, the force between the nucleus and the electron would be

• greater

• less

And if the distance between the nucleus and electron were greater the force would be (greater) or (less).

• greater

• less

If the distance between the nucleus and electron were doubled, the force would be

• 1/4 as much

• 1/2 as much

• two times as much

• 4 times as much

Consider the electric force between a pair of charged particles a certain distance apart. By Coulomb's law: a. If the charge on one of the particles is doubled, the force is

• unchanged

• halved

• doubled

• quadrupled

b. If, instead, the charge on both particles is doubled, the force is

• unchanged

• halved

• doubled

• quadrupled

c. If instead the distance between the particles is halved, the force is

• unchanged

• halved

• doubled

• quadrupled

d. If the distance is halved, and the charge of both particles is doubled, the force is __________ times as great.
