Question

select the correct terms to complete the statement about charged particles. the pattern that electrical forces show is that like charges attract | repel and opposite charges attract | repel. according to coulombs law, as the distance between two charged particles decreases, the force between the particles decreases | increases. as the magnitude of the charges decreases, the force decreases | increases.

Explanation:

• Like charges: According to the fundamental property of electric charges, like charges (e.g., two positive or two negative charges) repel each other.
• Opposite charges: Opposite charges (one positive and one negative) attract each other.
• Coulomb's law formula: Coulomb's law is given by \(F = k\frac{q_1q_2}{r^{2}}\), where \(F\) is the electrostatic force, \(k\) is a constant, \(q_1\) and \(q_2\) are the magnitudes of the charges, and \(r\) is the distance between the charges.
• Effect of distance: When the distance \(r\) between two charged particles decreases, since \(F\propto\frac{1}{r^{2}}\), the force \(F\) increases.
• Effect of charge magnitude: When the magnitude of the charges (\(q_1\) or \(q_2\)) decreases, since \(F\propto q_1q_2\), the force \(F\) decreases.

Answer:

repel, attract, increases, decreases
