The force responsible for the existence of the solar system is

Options

A. force of friction
B. gravitational force
C. electrostatic force
D. magnetic force

Answer

To solve the question regarding the force responsible for the existence of the solar system, we can analyze the options provided:

1. **Understanding the Question**: The question asks for the force that plays a crucial role in maintaining the structure and stability of the solar system.

2. **Evaluating the Options**:
- **Option 1: Force of Friction**: This force acts between surfaces in contact and is not relevant to the large-scale structure of celestial bodies.
- **Option 2: Gravitational Force**: This is the attractive force that acts between two masses. It is responsible for the orbits of planets around the sun and the overall structure of the solar system.
- **Option 3: Electrostatic Force**: This force acts between charged particles and does not play a significant role in the dynamics of celestial bodies.
- **Option 4: Magnetic Force**: While magnetic forces can influence charged particles, they do not govern the motion of planets and other celestial bodies in the solar system.

3. **Conclusion**: After evaluating all the options, the gravitational force is the only force that is responsible for the existence and stability of the solar system. It governs the motion of planets, moons, and other celestial bodies, keeping them in orbit around the sun.

**Final Answer**: The force responsible for the existence of the solar system is the **gravitational force**.
