Question

Which combination of charge and distance would lead to the strongest repulsive force ?

a + 1 charge and a -1 charge at a distance of 1.5 meters

a + 3 charge and a + 3 charge at a distance of 0.5 meters

a + 4 charge and a - 4 charge at a distance of 0.5 meters

a + 2 charge and a + 2 charge at a distance of 1.5 meters

The strongest repulsive force would be between the +4 charge and -4 charge at a distance of 0.5 meters. This is because the charges are larger and closer together, leading to a stronger repulsive force according to Coulomb's law.
