Question

what is the formula for coulombs law?

Explanation:

Step1: Recall Coulomb's law concept

Coulomb's law states that the magnitude of the electrostatic force \(F\) between two point charges \(q_1\) and \(q_2\) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance \(d\) between them. The formula is \(F = k_c\frac{q_1q_2}{d^2}\), where \(k_c\) is the Coulomb's constant.

Answer:

The formula \(F_{\text{electric}}=k_c\frac{q_1\times q_2}{d^2}\) (the second option in the given choices).
