Question

question 11 of 30
which force holds the nucleus of an atom together?

a. gravity

b. strong nuclear force

c. weak nuclear force

d. electrostatic force

Explanation:

• Option A: Gravity is extremely weak at atomic scales and does not hold the nucleus together.
• Option B: The strong nuclear force is the force that overcomes the electrostatic repulsion between protons in the nucleus and binds protons and neutrons together.
• Option C: The weak nuclear force is involved in processes like beta decay, not in holding the nucleus together.
• Option D: Electrostatic force causes repulsion between protons (since they are positively charged), so it can't hold the nucleus together.

Answer:

B. Strong nuclear force
