# Mark the Correct Statements - Physics

Short Note

Mark the correct statements :

(a) The nuclear force between two protons is always greater than the electromagnetic force between them.
(b) The electromagnetic force between two protons is always greater than the gravitational force between them.
(c) The gravitational force between two protons may be greater than the nuclear force between them.
(d) Electromagnetic force between two protons may be greater than the nuclear force acting between them.

#### Solution

(b) The electromagnetic force between two protons is always greater than the gravitational force between them.
(c) The gravitational force between two protons may be greater than the nuclear force between them.
(d) Electromagnetic force between two protons may be greater than the nuclear force acting between them.

The electromagnetic force between two protons is always greater than the gravitational force between them, because gravitational force is the weakest force in nature. We know that nuclear force is the strongest force in nature when the distance between two particles is less than ${10}^{- 14} m$ . However, the gravitational as well as electromagnetic forces between two protons may be greater than the nuclear force acting between them when the distance between them is more than ${10}^{- 14} m$

Is there an error in this question or solution?
