Question

Two objects are interacting under a particular type of force. If they repel each other, which of the forces could be responsible for this?

• A. Only magnetic force
• B. Only electrostatic force
• C. Either magnetic or electrostatic force
• D. Only gravitational force

Answer 1

The correct option is C Either magnetic or electrostatic force

Magnetic as well as electrostatic forces can be either replusive or attractive, which means either of these forces can be present between the objects.
Since, gravitational force is always attractive, it cannot be a cause of repulsion between the objects.
