To calculate the net force on the charge of -3 C at -2, we use Coulomb's law, which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The net force is the vector sum of the forces due to each charge.
First, we calculate the force due to the 2 C charge at -3:
Next, we calculate the force due to the 8 C charge at 6:
Since both charges exert attractive forces on the -3 C charge, we sum the forces:
Therefore, the net force on the charge of -3 C at -2 is N.

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.
