Question

Calculate the work done required to move an electron between two points A and B located at a potential difference of 100 V in an electric field.

Answer 1

Given Data:

Potential Difference (V) = 100 V

Charge of an electron (e) = 1.6 × 10⁻¹⁹ C

Formula:

The work done (W) in moving a charge (q) through a potential difference (V) is given by:

W = q × V

Substitute the values of charge and potential difference into the formula:

W = (1.6 × 10⁻¹⁹ C) × (100 V)

Simplify the expression:

W = 1.6 × 10⁻¹⁹ × 102 J

W = 1.6 × 10⁻¹⁷ J

The work done required to move the electron is 1.6 × 10⁻¹⁷ J.
