Apoint charge q1 = 4.10 nc is placed at the origin, and a second point charge q2 = -3.10 nc is placed on the x-axis at x=+ 20.0 cm . a third point charge q3 = 1.95 nc is to be placed on the x-axis between q1 and q2. (take as zero the potential energy of the three charges when they are infinitely far apart.)

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
