How does gravitation rank among the four basic forces of nature?
AIt is the second strongest
BIt is the weakest of the four
CIt is the strongest of the four
DIt is equal to the other three
Answer & Solution
Correct answer: B. It is the weakest of the four
1. Nature is described by four basic forces, and gravitation is one of them.
2. Of those four it is the weakest, and in some ways the least understood.
3. It nonetheless dominates on astronomical scales because it is always attractive and never cancels.
4. It also acts at a distance, with no physical contact needed between the bodies.
