Answer on Question #82404, Physics / Electromagnetism

Question:

1. Find the force between charges of $+10.0 \, \mu\mathrm{C}$ and $-50.0 \, \mu\mathrm{C}$ located $20.0 \, \mathrm{cm}$ apart.

Solution:

In accordance with Coulomb's law $F = \frac{k q_{1} q_{2}}{r^{2}}$, respectively $F = -\frac{9 \cdot 10^{9} \cdot 500 \cdot 10^{-12}}{0.2^{2}} = -112.5(N)$

The answer:

$\mathrm{F} = -112.5 \, \mathrm{N}$
