W15 Activity 1 - Intro. to Coulomb's Law

The force a charge experiences in an electric field can be found using the equation:

F = qE

Where q is the charge and E is the electric field.

Which best describes the direction of the force a charge experiences while in an electric field?

• The force is in the same direction as the E-field if the charge is positive, and opposite if the charge is negative.

• The force is in the same direction as the E-field if the charge is negative, and opposite if the charge is positive.

• The force is in the same direction as the E-field regardless if the charge is positive or negative.

• The force for the positive charge points downward.
