Which of the following radiations `alpha,beta and gamma` are :
similar to the nature of cathode rays ?

Explanation

To determine which of the following radiations—alpha, beta, and gamma—are similar to the nature of cathode rays, we need to analyze the properties of each type of radiation.

### Step-by-Step Solution:

1. **Understanding Cathode Rays**:
- Cathode rays are streams of electrons emitted from a cathode in a vacuum tube. They are negatively charged particles.

2. **Properties of Cathode Rays**:
