AThe strong nuclear force
BThe electromagnetic force
CThe weak nuclear force
DThe gravitational force
Answer & Solution
Correct answer: D. The gravitational force
1. Among the four basic forces, gravity is listed as attractive only.
2. The other three can be attractive or repulsive.
3. Electromagnetic forces nearly cancel for macroscopic objects because they come in both signs.
4. Gravity never cancels that way, so its pull accumulates with mass and we feel it directly.
