Question

Two positive charges q1 and q2 are separated by a distance r. The charges repel each other with a force F. If the magnitude of each charge is doubled and the distance stays unchanged, what is the new force between the charges?

Answer on Question #84543, Physics / Electromagnetism

**Question:**

Two positive charges q1 and q2 are separated by a distance r. The charges repel each other with a force F. If the magnitude of each charge is doubled and the distance stays unchanged, what is the new force between the charges?

**Solution:**

Following the Coulomb's law:

$$F = \frac{k q_1 q_2}{r^2}$$

, we can conclude that the new force $f = 4F$.

**The answer:**

The new force $f = 4F$.
