Use Coulomb's Law: ( F = \frac{k \cdot |q_1 \cdot q_2|}{r^2} ) where ( k ) is Coulomb's constant (8.99 × 10^9 N m²/C²), ( q_1 ) and ( q_2 ) are the charges, and ( r ) is the distance between them.

[ F = \frac{(8.99 \times 10^9) \cdot |-2 \cdot (-4)|}{(6 - (-3))^2 + ((-5) - (-9))^2} ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
