Question

Which of the following is/are characteristics of nuclear forces?

• A. These forces operate within small distances of $2\times {10}^{-13}cm$
• B. These forces drop to zero rapidly at a distance greater than $1.4\times {10}^2$ fermi
• C. They follow inverse square law
• D. They are stronger than electrostatic forces of attraction

Answer 1

Answer: (A), (B), (D)

These forces operate within small distances of $2\times {10}^{-13}cm$
They are stronger than electrostatic forces of attraction
These forces drop to zero rapidly at a distance greater than $1.4\times {10}^2$ fermi

Characteristics of nuclear forces :

$-$these forces operate within small distances of $2\times {10}^{-15}m$.

$-$these force drop to zero rapidly at a distance greater than $1.4\times {10}^2$ fermi.

$-$these forces don't follow increase square law as they operate in very small range.

$-$these are stronger than electrostatic forces pf attraction.
