Coulomb's Law is given by the formula

F=kq1q2/d2

The force F between two charges q1 and q2 in a vacuum is proportional to the product of the charges, and is inversely proportional to the square of the distance d between the two charges. Solve the formula for k.

Respuesta :

Here, we are required to solve for k from the formula, F=kq1q2/d².

Solving the formula for k, we obtain;

k = Fd²/q1q2

To solve the formula for k, we need to make k the subject of the formula;

  • From F = kq1q2/d².
  • Then, F × d² = kq1q2
  • Therefore, to make k the subject of the formula; we divide both sides of the equation by q1q2.

Therefore, k = Fd²/q1q2.
