Which changes will decrease the electric force between two positively charged objects? check all that apply. moving them closer together moving them farther apart adding electrons removing electrons adding neutrons removing neutrons

1. moving them farther apart

2. Adding electrons

Explanation:

The electric force between two positively charged particle is given by :

Where

k is the electrostatic constant

r is the distance between charges

The electric force is inversely proportional to the distance between them. So, the electric force between two positively charged objects will decrease when the charged particles move father apart. Also, on adding electrons, the magnitude of charges will decrease.

Hence, the correct options are (b) and (c).
