A uniform electric field of 500. V/m is directed in the negative x direction. A +15ìC charge moves from the origin to the point (x,y) = (20.0 cm, 50.0 cm). (a) what was the change in the potential energy of this charge? (b) Through what potential difference did the charge move?
This is how i worked it out and it is incorrect.Please tell me what step is incorrect.
Is the sign right on the .2 meters? The charge went against the field. Otherwise, it is ok.
