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

Answer 1

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

Answer 2

The strongest repulsive force would be between a +4 charge and a -4 charge at a distance of 0.5 meters. This is because the magnitude of the charges (4) is greater than any other combination, and the distance is smaller, leading to a stronger force according to Coulomb's law.

Answer 3

You're wrong, that would be the strongest attractive force

Answer 4

You are correct, I apologize for my mistake. The strongest repulsive force would be between a +3 charge and a +3 charge at a distance of 0.5 meters because the magnitude of the charges (3) is higher than any other combination given, and the distance is smaller than the other options. According to Coulomb's law, the strength of the repulsive force decreases as the distance between the charges increases.

Answer 5

An electromagnet can be made by wrapping coils of wire around a nail and running a current through the wire. How can the strength of the electromagnet be maximized ? (1 point ) The thickness of the nail and number of coils around the nail should be maximized .

The length and thickness of the nail should be maximized

. The current and length of the nail should be maximized .

The current and number of coils around the nail should be maximized .
