Suppose the an electron in the picture tube of a televisoin set is accelerated from rest through a potential differnece `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 given problem, 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}
