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.

What direction is the force the negative charges experience while in the E-field shown in the image?
The force for the negative charges points to the left
The force for the negative charges points to the right
The force for the negative charges points upward
The force for the negative charges points downward.
What direction is the force the positive charge experiences while in the E-field shown in the image?
The force for the positive charge points to the left
The force for the positive charge points to the right
The force for the positive charge points upward
The force for the positive charge points downward.
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.
