Question

If $F_{p-p},F_{p-n},F_{n-n}$ are nuclear forces between two protons, a proton and a neutron and two neutrons respectively inside a nucleus, then

• A. $F_{p-p}<F_{p-n}<F_{n-n}$
  
• B. $F_{p-p}=F_{p-n}=F_{n-n}$
  
• C. $F_{p-p}<F_{p-n}=F_{n-n}$
  
• D. $F_{p-p}>F_{p-n}=F_{n-n}$
  

Answer 1

The correct option is B $F_{p-p}=F_{p-n}=F_{n-n}$


The nuclear forces are charge independent and always attractive.

So, the nuclear force between two protons, a proton and a neutron and two neutrons will be the same inside the nucleus.

Hence, option $\left(B\right)$ is correct.
