What is the electric force between a +2 µC point charge and a –2 µC point charge if they are separated by a distance of 5.0 cm? Show your work. (µC = 1.0 × 10–6 C)

Question

matt101 · Answer

You can solve this using Coulomb's Law. Just be sure you're using the correct units!

$$F={kq_1q_2 \over r^2}$$

Thanks, can you tell me what those letter stand for though. I'm really bad in physics..

F is referring to the electric force (in N)
k is Coulomb's constant
The two q's are the two charges (in C)
r is the distance between the charges (in m)
