Suppose an electron in the picture tube of a television set is accelerated from rst through a potential differencre `V_(b) - V_(a) = V_(ba) =+` 5000V
(a) What is the change in electric potential energy of the electron?
(b) What is the speed of the electron `(m = 9.1 xx 10^(31)kg)` as a result of this acceleration?

Explanation

To solve the problem step by step, we will break it down into two parts as specified in the question.

### Part (a): Change in Electric Potential Energy of the Electron

1. **Identify the charge of the electron**:
The charge of an electron \( Q \) is given as:
\[
Q = -1.6 \times 10^{-19} \, \text{C}
