A uniform electric field of magnitude 200 V/m is directed in the positive x -dir

Question

A uniform electric field of magnitude 200 V/m is directed in the positive x-direction. A 19 µC charge moves from the origin to the point (x, y) = (20 cm, 50 cm).

m (beyond the -4.00 ? 10-9 C charge)

A uniform electric field of magnitude 200 V/m is directed in the positive x-direction. A 19 mu C charge moves from the origin to the point (x, y) = (20 cm, 50 cm). What was the change in the potential energy of this charge? J Through what potential difference did the charge move? V A charge of 5.50 ? 10-9 C and a charge of -4.00 ? 10-9 C are separated by a distance of 60.0 cm. Find the position at which a third charge, of 13.0 ? 10-9 C, can be placed so that the net electrostatic force on it is zero. m (beyond the -4.00 ? 10-9 C charge)

Explanation / Answer

(a) What was the change in the potential energy of this charge?

DPE = -qEd = -(+19
