Answer:

B) -2 Coulombs

Explanation:

In order to find the net charge, we must add the charge that you have with the charge that your friend has, but taking into account the different sign. In fact, we have:

- Charge possessed by you: Q1 = +3 C

- Charge possessed by your friend: Q2 = -5 C

Therefore, the net charge possessed by both persons will be given by

Q = Q1 + Q2 = +3 C + (-5 C) = +3 C - 5 C = -2 C
