The diagrams below in which arrows indicate the direction of movement represent charged particles placed near one another. The diagram that correctly represents the motion of the charged particles

Diagrams 3 and 4.

Explanation:

The force that one charge q1 experiences when is at a distance R of another charge q2 is:

F = k*(q1*q2)/R^2

Where k is a constant.

If this force is positive, the chares move away from each other, so if both charges are positives or both charges are negatives, then the charges move away from each other, meaning that the force is repulsive.

If the force is negative, the force is towards the other particle, then the force is attractive. This happens when one charge is positive and the other is negative.

Then the correct options are 3 and 4.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
