Question

An electron in an old television picture tube

passes through a potential difference of
18,000 V. How much work is done on the
electron as it passes through that potential
difference?

Answer 1

The work done on the electron is -2.88 x 10^-15 J.

Step-by-step explanation:

The work done on an electron as it passes through a potential difference can be calculated using the equation: Work = Charge x Voltage.

In this case, the charge of an electron is -1.6 x 10-19 C and the potential difference is 18,000 V. Therefore, the work done on the electron is:

Work = (-1.6 x 10-19 C) x (18,000 V) = -2.88 x 10-15 J.
