Aparticle has a charge of +1.5 µc and moves from point a to point b, a distance of 0.15 m. the particle experiences a constant electric force, and its motion is along the line of action of the force. the difference between the particle's electric potential energy at a and b is epea - epeb = +9.0 10-4 j.
(a) find the magnitude and direction of the electric force that acts on the particle. the direction of motion (along, against, perpendicular)
(b) find the magnitude and direction of the electric field that the particle experiences. /c the direction of motion (along, against, perpendicular)

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
