Answer :

Answer:

The student is referring to Coulomb's Law, which states that the electric force (F) between two charges is given by the formula:

F = k * q1 * q2 / r²

Here, F is the electric force, k is Coulomb's constant (8.99 x 109 N·m²/C²), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

  1. To find a charge q (either q1 or q2), you need the values of the other variables. Let's solve for q1:
  2. Rearrange the equation to isolate q1: q1 = F * r² / (k * q2)
  3. Substitute the known values of F, r, and q2 to find q1.
