Question

electrostatic charge/coulombs law assignment

1. like charges exert an attractive force, opposite charges exert a ____________ force.

a positive
b frictional
c negative
d repulsive

Explanation:

Coulomb's Law states that like electric charges exert repulsive forces on each other, while opposite electric charges exert attractive forces. The question incorrectly states like charges are attractive, but the blank asks for the force between opposite charges, which is the inverse of the (incorrectly stated) like charge force. The correct force type for opposite charges is attractive, but since the question frames like as attractive, it is asking for the opposite force, which is repulsive.

Answer:

D. repulsive
