An electron , with charge of `-1.60 xx 10^(19) C`, accelerates from rest through a potential difference V. A proton , with a charge of `+ 1.60 xx 10^(-19) C `, accelerates from rest through a potential difference `-V` . Is the final speed of the electron (a) more than , (b) less than , or (c ) same as the final speed of the proton ?

Explanation

To determine whether the final speed of the electron is more than, less than, or the same as the final speed of the proton when both are accelerated through their respective potential differences, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- An electron with charge \( q_e = -1.60 \times 10^{-19} \, C \) accelerates through a potential difference \( V \).
- A proton with charge \( q_p = +1.60 \times 10^{-19} \, C \) accelerates through a potential difference \( -V \).
- We need to compare their final speeds after acceleration.
