Question

How much work is required to move an electron

through a potential difference of 3.00 volts?

(1) 5.33 × 10^–20 J (3) 3.00 J

(2) 4.80 × 10^–19 J (4) 1.88 × 10^19 J

Answer 1

(2) the work required to move the electron is 4.8 x 10⁻¹⁹ J.

Step-by-step explanation:

Given;

potential difference, V = 3.00 volts

charge of electron, q = 1.6 x 10⁻¹⁹ C

The work required to move an electron is calculated as;

W = Vq

where;

W is the work done in Joules

Substitute the given values and solve for W;

W = (3.00)(1.6 x 10⁻¹⁹)

W = 4.8 x 10⁻¹⁹ J.

Therefore, the work required to move the electron is 4.8 x 10⁻¹⁹ J.
