Question

Assertion :Two protons and two neutrons are each separated by a distance of $r={10}^{-14}$ m which is the size of the nucleus. Hence the force between two neutrons will be greatest. Reason: At distances of the order of ${10}^{-14}$ m neutrons and protons exert very strong attractive forces on each other and this force does not depend on the charge.

• A. Statement I is True and Statement 2 is True and is a correct explanation of Statement 1.
• B. Statement I is True and Statement 2 is True but not a correct explanation of Statement 1.
• C. Statement I is True and Statement 2 is False
• D. Statement I is False and Statement 2 is True.

Answer 1

The correct option is A Statement I is True and Statement 2 is True and is a correct explanation of Statement 1.

(Nuclear forces)
At a very small distances, in the order of ${10}^{-14}m$ or lesser, the neutrons and protons are held together by altogether new type of forces called as Nuclear force one of its properties is also that it is independent of the charge present on the material and is only attractive in nature and is huge amount of force as compared to coulombs force.
