. Calculate the number of electrons that must be removed from an uncharged object to give it a positive charge of 3.8 x 10-14 C. KU Calculate the magnitude of the electric field and the electric potential at a distance of 0.35 m from an object with an excess of 6.1 X 10ʻ electrons. A Consider two parallel plates 2.00 mm apart witha potential difference of 240 V and a positivelycharged upper plate. A charged oil droplet with amass of 5.88 X 10-1º kg is suspended between theplates. Determine the sign and magnitude of theelectric charge on the oil droplet, and calculate theelectron deficiency or excess. A
