What potential difference must be applied to produce an electric field that can accelerate an electron to 1/10 of velocity of light.

Explanation

To solve the problem of finding the potential difference required to accelerate an electron to 1/10 of the velocity of light, we can follow these steps:

### Step-by-Step Solution

1. **Understand the Problem**: We need to find the potential difference \( V \) that will accelerate an electron to a speed \( v' = \frac{c}{10} \), where \( c \) is the speed of light.

2. **Identify Relevant Equations**:
- The kinetic energy (KE) of the electron when it reaches the desired speed is given by:
