Which fundamental force is the unification of two forces?

A. Gravity

B. Electromagnetic force

C. Strong nuclear force

D. Weak nuclear force

B. Electromagnetic force

Explanation:

Electromagnetic force is the unification of two forces

1) Electrostatic force

2) Magnetic force

here we know that electrostatic force is the force of attraction or repulsion due to two static charges placed near to each other

Magnetic force is the force between two magnetic material or two moving charges which produce magnetic field near each other

So unification of two fundamental forces is used in case of electromagnetic force.

Hello.

The answer is: Electromagnetic force

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Have a nice day.
