QUESTION:
Shown are three separate pairs of point charges. Assume the pairs interact only with each other. Rank the magnitudes of the forces between the pairs, from largest to smallest.
ANSWER:
Step 1 of 5
Figure shows three separate pairs of point charges
Coulomb's law states that the magnitude of the electric force between two stationary charges is directly proportional to the magnitude of the product of the two charges and inversely proportional to the square of the distance between them. The force is directed along the line joining between the two charges.
We need to find forces for those 3 situations, and then compare magnitudes of forces, and rank them. Formula for force is
