Neutrino is a particle, which is

Options

A. Charge less and has spin
B. Charged and has spin
C. Charged and has no spin
D. Charge less and has no spin

Answer

To solve the question about neutrinos, we need to analyze the properties of neutrinos based on our understanding of particle physics. Here’s a step-by-step breakdown:

### Step 1: Understand the Nature of Neutrinos
Neutrinos are subatomic particles that belong to the lepton family. They are known for their very small mass and their lack of electric charge.

### Step 2: Identify the Properties of Neutrinos
1. **Charge**: Neutrinos are chargeless, meaning they do not carry any electric charge.
2. **Spin**: Neutrinos possess intrinsic angular momentum known as spin. They have a spin of \( \frac{1}{2} \), which classifies them as fermions.

### Step 3: Analyze the Options Given in the Question
The options provided are:
- A) Chargeless and has spin
- B) Charged and has spin
- C) Charged and has no spin
- D) Chargeless and has no spin

From our understanding:
- Neutrinos are **chargeless** (no electric charge).
- Neutrinos have **spin** (specifically, they have a spin of \( \frac{1}{2} \)).

### Step 4: Select the Correct Option
Based on the properties identified:
- Option A states that neutrinos are "chargeless and has spin," which aligns with our understanding of neutrinos.

Therefore, the correct answer is **Option A: Chargeless and has spin**.

### Summary of Solution
Neutrinos are particles that are chargeless and possess spin, making Option A the correct choice.
