The weight of a body is__________

Options

A. the same every where on the earth.
B. the gravitational force experienced by the body.
C. the mass of the body.
D. independent of mass of the body.

Explanation

**Step-by-Step Solution:**

1. **Understanding Weight**: Weight is defined as the force exerted by gravity on an object. It is a measure of how much gravitational force is acting on that object.

2. **Formula for Weight**: The weight (W) of a body can be calculated using the formula:
\[ W = m \times g \]
where:
- \( W \) is the weight of the body,
- \( m \) is the mass of the body,
- \( g \) is the acceleration due to gravity.

3. **Role of Mass and Gravity**: The weight of an object depends on two factors:
- The mass of the object (which is constant).
- The acceleration due to gravity (g), which can vary depending on the location on Earth.

4. **Variation of 'g'**: The value of \( g \) is not the same everywhere on Earth. For example:
- At the equator, the value of \( g \) is slightly less than 9.8 m/s².
- At the poles, the value of \( g \) is slightly more than 9.8 m/s².
This means that the weight of the same object can change depending on where it is located on Earth.

5. **Conclusion**: Therefore, the weight of a body is not the same everywhere on Earth. It varies with the change in the value of \( g \).

**Final Answer**: The weight of a body is the gravitational force acting on it, calculated as \( W = m \times g \), and it varies depending on the location due to changes in \( g \).
