Which of the following forces is not fundamental force in nature 1. Gravitational force 2.Electromagnetic force 3.Strong nuclear force 4.Tension?

Options

A. Gravitational force
B. Electromagnetic force
C. Strong nuclear force
D. Tension

Explanation

To determine which of the following forces is not a fundamental force in nature, let's analyze each option provided:

1. **Gravitational Force**: This is a fundamental force that acts between two masses. It is described by Newton's law of gravitation, which states that the force of attraction between two masses is proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, gravitational force is a fundamental force.

2. **Electromagnetic Force**: This is another fundamental force that acts between charged particles. It can be attractive or repulsive depending on the nature of the charges involved. Since it governs the interactions between charged particles, it is also considered a fundamental force.

3. **Strong Nuclear Force**: This force acts between nucleons (protons and neutrons) within an atomic nucleus. It is responsible for holding the nucleus together and is classified as a fundamental force in nature.

4. **Tension**: Tension is not a fundamental force. Instead, it is a force that arises from the interaction of objects, typically in a string or rope when it is pulled. Tension is a result of the forces acting on the objects connected by the rope or string, and it does not exist independently as a fundamental force.

Based on this analysis, the answer to the question is:

**Answer**: 4. Tension is not a fundamental force in nature.
