Question

3.1.4 quiz: noncontact forces
question 10 of 10
coulombs law describes how the charge on and distance between two particles affect the electric force between them. which situation will result in two particles being repelled by each other?
a. decreasing the distance between them
b. both particles having a positive charge
c. increasing the distance between them
d. one particle having a positive charge and the other a negative charge

Explanation:

Like - charges repel each other. Opposite - charges attract. Decreasing or increasing distance affects the force magnitude but not the direction of the force (attraction or repulsion). When both particles have positive charges, they will repel each other according to Coulomb's law.

Answer:

B. Both particles having a positive charge
