Question

Name two forces in nature that have the longest and shortest range.

Answer 1

Hint: Remember that there are four fundamental forces in nature
1) Gravitational force
2) Electromagnetic force
3) Weak Nuclear force
4) Strong nuclear force.
Differentiate all the forces based on the range of forces acting and try to find the strong forces.

Complete step by step answer:
Range is defined as the distance to which a certain type of force may act on a body.
So, among the four fundamental forces in nature, the forces according to their shortest and longest ranges are -
a) The longest range of operation: gravitational force

b) Shortest range of operation: strong nuclear force.

Note:Gravitational Force: This force is the weakest but has an infinite range. This force is always attractive in nature. It is dependent upon the mass of the two bodies and the distance between them.
Strong Nuclear Force: This force holds the nucleus of an atom together. It is the strongest of the forces, but it is very short ranged. This force is also attractive in nature.
Weak Nuclear Force: This force is weaker as compared to the strong nuclear force. All particles experience this force.
Electromagnetic Force: This is the second strongest force after the strong nuclear force and it acts on electrically charged particles. This force has both attractive and repulsive properties due to the two charges it possesses; negative and positive. It is also an infinite ranged force.
