The points A and B are separated by a distance of 42 cm dominated by an external electric field of 400 N/C directed toward the right. If a point charge of 40 mC moves from A to B, calculate the change in the electric potential energy of the charge.

pi x^2

step-by-step explanation:

pi times x squared
