Interaction C

Interaction B

Interaction A and B

Interaction C and D

Answer 1

The correct answer is Interaction C, because when two objects have charges with the same sign (in this case both are positive), they will repel each other. Therefore, Interaction A and D will have a repulsive electrical force, while Interaction B has no net electrical force since the charges are equal in magnitude and opposite in sign. Interaction C, with one positively charged object and one negatively charged object, will have an attractive electrical force.
