Question

question 20: what are the four fundamental forces of the universe?

• strong nuclear force, weak nuclear force, friction, gravity
• strong nuclear force, weak nuclear force, electromagnetism, gravity
• nuclear force, gravity, electromagnetism, friction
• gravity, applied force, tension, normal force

Explanation:

Identify the four fundamental interactions

The four fundamental forces of nature are gravity, electromagnetism, the weak nuclear force, and the strong nuclear force.

Evaluate the given options

• Option 1: Includes friction, which is a macroscopic contact force derived from electromagnetism.
• Option 2: Correctly lists the strong nuclear force, weak nuclear force, electromagnetism, and gravity.
• Option 3: Includes friction, which is not a fundamental force.
• Option 4: Includes applied force, tension, and normal force, which are all macroscopic contact forces.

Answer:

• (A) Strong Nuclear Force, Weak Nuclear Force, Friction, Gravity
• (B) Strong Nuclear Force, Weak Nuclear Force, Electromagnetism, Gravity (Correct answer)
• (C) Nuclear Force, Gravity, Electromagnetism, Friction
• (D) Gravity, Applied Force, Tension, Normal Force
