Problem 1) Two charges of equal magnitude (5x10^-9) are on the x-axis; q1 is neg and q2 is pos. a) Find electric field E at point P above the x axis, 7 m from each charge, so that the line to each makes a 30 degree angle with the x-axis. b) find potential V at P. c) How much work is required for a person to bring a 3 microcoulomb charge to P from far away.
Problem 2) A capacitor (C=3 microf) is connected to a 24 volt battery. a) Find charge and voltage on the capacitor. b) if capacitor is disconnected form battery and a dielectric (K=1.5) is placed between the plates, find charge and voltage on the capacitor. c) What is the main purpose of placing a dielectric in a capacitor? Give any other reason(s)?
