What work is done by an electrostatic field when a 100 C charge moves over a distance of 20 meters

What work is done by an electrostatic field when a 100 C charge moves over a distance of 20 meters with a potential difference between the start and end points of 40 V?

To find the amount of work performed by a given electrostatic field, we use the formula: A = q * Δφ.

Variables: q – displaced charge (q = 100 C); Δφ is the potential difference (Δφ = 40 V).

Let’s perform the calculation: A = q * Δφ = 100 * 40 = 4 * 10 ^ 3 J.

Answer: To move the charge, a given electrostatic field performed work of 4 kJ.
