Question
Two point charges are separated by a distance $r$. If the separation is reduced by a factor of 1.5, by what factor does the electric force between them change?
Step 1
Step 1: The initial force between the two point charges is given by Coulomb's law as $F = \frac{{kQ_1Q_2}}{{r^2}}$, where $k$ is Coulomb's constant, $Q_1$ and $Q_2$ are the charges, and $r$ is the initial separation. Show more…
