Question

question 27 of 30
what force pulls electrons and protons together?

a. friction
b. weak nuclear force
c. gravity
d. electrostatic force

Explanation:

• Option A: Friction is a force between two surfaces in contact, not related to electrons and protons.
• Option B: Weak nuclear force is involved in radioactive decay, not in pulling electrons and protons together.
• Option C: Gravity is a very weak force between masses and is negligible at the atomic level for electrons and protons.
• Option D: Electrostatic force (Coulomb's force) acts between charged particles. Electrons are negative and protons are positive, so the electrostatic attraction between them pulls them together.

Answer:

D. Electrostatic force
