Consider the situation of the previous problem. Consider the fastest electron emitted parallel to the large metal plate. Find the displacement of this electron parallel to its initial velocity before it strikes the large metal plate.

Explanation

To solve the problem of finding the displacement of the fastest electron emitted parallel to the large metal plate before it strikes the plate, we can follow these steps:

### Step 1: Calculate the Electric Field
The electric field \( E \) can be calculated using the formula:
\[ E = \frac{\sigma}{\epsilon_0} \]
where:
