Step 1

First, we need to find the distance between each charge and point P. Let's call the distance from 41 to P as r1 and the distance from 4z to P as r2. Using the Pythagorean theorem, we have: $r1 = \sqrt{(0.08)^2 + (0.1)^2} = 0.128$ m $r2 = \sqrt{(0.08)^2 + (0.1)^2} Show more…

Point charges q1 = 12 μC and q2 = -12 μC are 0.08 m apart as shown in the Figure. Compute the electric fields caused by q1 and q2, and the total field at point P (E1, E2, Et = ?). Compute the force exerted on a test charge of q = -5 μC placed at point P.
