Question

Arrange the following basic forces in the increasing order of relative strength

1. Gravitational force

2. Electromagnetic force

3. Weak nuclear force

4. Strong nuclear

• A. 1, 2, 3, 4
• B. 1, 3, 2, 4
• C. 4, 3, 2, 1
• D. 4, 1, 2, 3

Answer 1

Answer: (B)

1, 3, 2, 4

Answer 2

Name of forces	Relative strength
Gravitational forces	$10^{- 39}$
Weak nuclear forces	$10^{- 13}$
Electromagnetic forces	$10^{- 2}$
Strong nuclear forces	1

Thus, the correct order is 1, 3 2, 4.
