The weight of a body will increase significantly it is taken

Options

A. from the pole of the equator
B. from the equator to the pole
C. to the top of a momentum
D. to the centre of the earth

Answer

To solve the question regarding the change in weight of a body as it is moved from the equator to the pole, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Weight and Gravity**:
- Weight (W) of a body is given by the formula:
\[ W = mg \]
where \( m \) is the mass of the body and \( g \) is the acceleration due to gravity.

2. **Acceleration due to Gravity**:
- The value of \( g \) varies with latitude due to the Earth's rotation and its shape. The formula for \( g \) at a latitude \( \theta \) is:
\[ g' = g - R_e \omega^2 \cos^2(\theta) \]
where:
- \( g' \) is the effective gravity at latitude \( \theta \),
- \( R_e \) is the radius of the Earth,
- \( \omega \) is the angular velocity of the Earth.

3. **Evaluating at the Equator**:
- At the equator, \( \theta = 0^\circ \):
\[ g' = g - R_e \omega^2 \cos(0) = g - R_e \omega^2 \]
Hence, \( g' \) is minimum at the equator.

4. **Evaluating at the Pole**:
- At the pole, \( \theta = 90^\circ \):
\[ g' = g - R_e \omega^2 \cos(90) = g - 0 = g \]
Thus, \( g' \) is maximum at the pole.

5. **Comparing Weights**:
- As we move from the equator to the pole, \( g' \) increases from its minimum value at the equator to its maximum value at the pole.
- Since weight is directly proportional to \( g \), the weight of the body will also increase as it moves from the equator to the pole.

6. **Conclusion**:
- Therefore, the weight of a body will increase significantly when taken from the equator to the pole.

### Final Answer:
The weight of a body will increase significantly if it is taken from the equator to the pole.
