MCQ practice · SSC Physics Board questions · Chapter 3: Force
The electroweak force is formed by the combination of which two fundamental forces?
Think it through first, then pick an option.
- a gravitational force and electric force
- b strong nuclear force and weak nuclear force
- c electromagnetic force and weak nuclear force
- d gravitational force and strong nuclear force
Answer and explanation
Correct answer: c electromagnetic force and weak nuclear force
The electromagnetic and weak nuclear forces were explained by one law, called the electro-weak force.
Why the other options are wrong
- a gravitational force and electric force: Gravity is not part of this single law; the book keeps it separate.
- b strong nuclear force and weak nuclear force: The two nuclear forces together do not make the electro-weak force; the electromagnetic force is in it.
- d gravitational force and strong nuclear force: The book does not join gravity and the strong nuclear force in any single law.
