Answer 2

Option(b), (c), (d) are the correct statements, when the distance between two protons are greater.

Explanation:

• In Earth, the order of forces is, strong Nuclear force, electromagnetic force, weak nuclear force and gravitational force.
• The weakest of all the force is gravitational force and the strongest is nuclear force
• Electromagnetic force is stronger than gravitational force - Between two protons the electromagnetic force is greater than gravitational force.
• Range of an electromagnetic force is longer than the rang of the strongest nuclear force - Between two protons the electromagnetic force is greater than Nuclear force.
• Gravitational force can be acted on many other objects but the Nuclear force can act up on protons and neutrons.

$\text{Electromagnetic force between two protons} = \frac{23.04 \times 10^{-29}}{r^{2}} N$

$\text {The gravitational force between two protons} = \frac{6.674 \times 10^{-73}}{r^{2}} N$

$\text {Nuclear force between two protons} =-H \frac{-e^{s / s_{0}}}{s^{2}}$

$where, s_{0}=1.522 \mathrm{fermi}$

$\text{and} H=3.4 \times 10^{-26}$

Nuclear force is lesser than electromagnetic force and gravitational force when the distance between the protons are greater.
