Question

Two objects repel each other. This repulsion could be due to

• A. frictional force only.
• B. electrostatic force only.
• C. magnetic force only.
• D. either a magnetic or an electrostatic force.

Answer 1

Answer: (D)

Frictional force is applied along the surfaces and depends on contact. hence it is not a repulsive force.

Electrostatic and magnetic forces can be either attractive or repulsive. Here, when two objects are experiencing repulsive force because there may be an electrostatic force or a magnetic force.
