Question

Which of the four fundamental forces is the weakest force? • a. electrostatic force b. weak nuclear force • c. force of gravity • d. strong nuclear force

Answer 1

Gravity is the weakest of the four fundamental forces, particularly at the atomic and subatomic scales.

Step-by-step explanation:

The weakest of the four fundamental forces is gravity. Although gravity is strong on a macroscopic scale, it is much weaker compared to the other three forces at the atomic and subatomic scales. For example, the electromagnetic force is much stronger than gravity and is responsible for holding atoms together.

Answer 2

The weakest of the four fundamental forces is the gravitational force, which is significantly weaker than the electromagnetic force, the weak nuclear force, and the strong nuclear force. So the correct option is c.

Step-by-step explanation:

The question asks which of the four fundamental forces is the weakest. According to our knowledge of physics, the force of gravity is by far the weakest of the four. In contrast, the electromagnetic force, the weak nuclear force, and the strong nuclear force are significantly more powerful.

Comparing the Fundamental Forces

Here's how the four fundamental forces rank from strongest to weakest:

1. Strong nuclear force
2. Electromagnetic force
3. Weak nuclear force
4. Gravity

For an example of when gravity can be considered the dominant force, we can look at large-scale phenomena such as the structure of galaxies, the movement of planets, or falling objects on Earth, where other forces play a negligible role.

Therefore, the correct answer is c. the gravitational force.
