Statement-I : When X-ray incident on metal, the ejection of electron shows the particle nature of X-ray.
Statement-II : X-ray is positively charged particle.

Options

A. If both Statement- I and Statement- II are true, and Statement - II is the correct explanation of Statement– I.
B. If both Statement - I and Statement-II are true but Statement - II is not the correct explanation of Statement – I.
C. If Statement-I is true but Statement-II is false.
D. If Statement-I is false but Statement-II is true.

Answer

To solve the given question, we will analyze both statements and determine their validity.

### Step 1: Analyze Statement-I
**Statement-I:** When X-ray incident on metal, the ejection of electron shows the particle nature of X-ray.

- X-rays are a form of electromagnetic radiation, which can behave like particles (photons) under certain conditions. When X-rays strike a metal surface, they can impart enough energy to eject electrons from the metal. This phenomenon is known as the photoelectric effect.
- The ejection of electrons due to X-ray interaction indicates that X-rays possess particle-like properties, confirming that they can indeed behave as particles.

**Conclusion:** Statement-I is **True**.

### Step 2: Analyze Statement-II
**Statement-II:** X-ray is a positively charged particle.

- X-rays are not particles with charge; they are high-energy photons. Photons are neutral and do not carry any charge, whether positive or negative.
- Therefore, the assertion that X-rays are positively charged particles is incorrect.

**Conclusion:** Statement-II is **False**.

### Step 3: Determine the Relationship Between the Statements
- Since Statement-I is true and Statement-II is false, we conclude that the first statement does not require the second statement to be true for its validity.

### Final Answer
- Statement-I is true, and Statement-II is false. Thus, the correct option for this question will be option C.
