Question

The range of weak nuclear force is of the order of

• A. $10^{16}$ m
• B. $10^{-10}$ m
• C. $10^{10}$ m
• D. $10^{-16}$ m

Hint:

Memorize the relative strengths and ranges of the four fundamental forces. Strong Force: Range $\sim 10^{-15}$ m (size of a nucleus). Electromagnetic Force: Infinite range. Weak Force: Range $\sim 10^{-17}$ m. Gravitational Force: Infinite range.

Answer 1

The Correct Option is D

The weak nuclear force is one of the four fundamental forces of nature, alongside the strong nuclear force, electromagnetism, and gravitation.
It is responsible for radioactive decay processes like beta decay.
The range of a force is the characteristic distance over which it is effective.
The weak nuclear force has an extremely short range, significantly smaller than the size of an atomic nucleus.
Its range is typically quoted to be on the order of $10^{-18}$ meters to $10^{-16}$ meters.
Among the given options, $10^{-16}$ m is the correct order of magnitude for the range of the weak nuclear force.
