A small metal ball is suspended in a uniform electric field with the help of an insulated thread. If high energy X-ray beam falls on the ball, the ball will be deflected in the direction of the field.

Explanation

To solve the problem of why a small metal ball suspended in a uniform electric field is deflected in the direction of the field when a high-energy X-ray beam falls on it, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Initial Condition**:
- The small metal ball is initially neutral, meaning it has an equal number of protons and electrons. It is suspended in a uniform electric field, which we will denote as \( \vec{E} \).

**Hint**: Remember that a neutral object does not experience a net electric force in an electric field.
