Auniform electric field of magnitude 300 v/m is directed in the negative x-direction. a 20 µc, 10 ? g particle moves from the origin to the point (x, y) = (20 cm, 50 cm).
(a) through what electric potential difference did the particle move?

(b) what was the work done on this particle?

(c) if the particle's speed was 600 m/s at the origin, what is it's speed at the point (x, y) = (20 cm, 50 cm)?
/s

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
