What is the formula to find the second charge in Coulomb's Law?

1.F is the electrostatic force between charges (in Newtons),

2.q₁ is the magnitude of the first charge (in Coulombs),

3.q₂ is the magnitude of the second charge (in Coulombs),

4.r is the shortest distance between the charges (in m),

5.ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C² .

Explanation:

F is the electrostatic force between charges (in Newtons), 2. q, is the magnitude of the first charge (in Coulombs), 3. q2 is the magnitude of the second charge (in Coulombs), 4. r is the shortest distance between the charges (in m), 5. ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N-m²/C².
