Assertion: A point charge is brought in an electric field. The field at a nearby point will increase, whatever be the nature of the charge.
Reason: The electric field is independent of the nature of charge.

Options

A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. If Assertion is true but Reason is false
D. If both Assertion and Reason are false

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that when a point charge is brought into an electric field, the field at a nearby point will increase, regardless of the nature of the charge (positive or negative).
- To evaluate this, we consider a positive charge placed in an external electric field \(E_1\). The positive charge will create its own electric field \(E_2\) in the surrounding space.

2. **Analyzing the Electric Field**:
- The total electric field at a point near the positive charge will be the vector sum of the external electric field \(E_1\) and the electric field due to the positive charge \(E_2\).
- In the direction of the external field, the total electric field will be \(E_1 + E_2\) (increasing).
- In the opposite direction, the total electric field will be \(E_1 - E_2\) (which could decrease if \(E_1\) is smaller than \(E_2\)).
- Therefore, the assertion is incorrect because the electric field does not uniformly increase at all nearby points.

3. **Understanding the Reason**:
- The reason states that the electric field is independent of the nature of the charge.
- This means that the effect of the charge (positive or negative) does not influence the total electric field produced.
- However, when we analyze the scenario with a negative charge, we find that the electric field contributions differ based on the nature of the charge.
- For a negative charge, the electric field at a point in the direction of the external field will be \(E_1 - E_2\) and in the opposite direction will be \(E_1 + E_2\).
- This shows that the total electric field indeed depends on the nature of the charge, making the reason incorrect.

4. **Conclusion**:
- Since both the assertion and the reason are incorrect, the final answer is that both the assertion and the reason are false.

### Final Answer:
Both the assertion and the reason are false.
