Sure, let's break this down step by step:

1. First, we need to multiply the charges together. The charges are +2 C and -1 C. When we multiply these together, we get -2 C^2.

2. Next, we multiply this result by the constant 9 × 10^9 N m^2/C^2. This gives us -18 × 10^9 N m^2.

3. Finally, we divide this result by the square of the distance, which is (4 m)^2 = 16 m^2.

So, (-18 × 10^9 N m^2) / (16 m^2) = -1.125 × 10^9 N.

So, the force between the two charges is -1.125 × 10^9 N. The negative sign indicates that the force is attractive.
