Question

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)

Answer 1

use coulumbs law
\[F = \frac{k \ q_1 \ q_1}{r^2}\]
where k is coulumbs constant 9 x 10^9

Answer 2

Thank you so much!
