R : An electron is a point charge.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To solve the assertion-reason question, we need to analyze both the assertion (A) and the reason (R) provided.

**Assertion (A):** Since matter cannot be concentrated at a point, therefore point charge is not possible.

**Reason (R):** An electron is a point charge.

### Step-by-Step Solution:

1. **Understanding Point Charges:**
- A point charge is an idealized model where all the charge is concentrated at a single point in space. This means it has no physical size or volume.
- In reality, matter has mass and occupies space. Therefore, it cannot be concentrated at a single point without leading to infinite density.

2. **Analyzing Assertion (A):**
- The assertion states that since matter cannot be concentrated at a point, point charges are not possible. This is true because if we try to treat a physical object as a point charge, we would imply that its volume is zero, leading to an undefined or infinite density (mass/volume).
- Hence, the assertion is **true**.

3. **Analyzing Reason (R):**
- The reason states that an electron is a point charge. While electrons are often treated as point charges in physics, they are not truly point-like in a physical sense. Electrons have properties of both particles and waves (wave-particle duality), and they do not have a defined physical size.
- Therefore, while we can treat electrons as point charges for many calculations, they do not fit the strict definition of a point charge because they have wave-like properties and cannot be localized to a single point without considering their quantum nature.
- Thus, the reason is **false**.

4. **Conclusion:**
- Since the assertion is true and the reason is false, the correct answer is that statement 1 (A) is true, but statement 2 (R) is false.

### Final Answer:
- The answer is **C**: Statement 1 is true, but statement 2 is false.
