Q1. If you were to separate all of the electrons and protons in 1g (0.001kg) of matter, you'd have about 96,000 C of positive charge and the equal amount of negative charge. If you placed these charges 1m apart, how strong would the attractive forces between them be?
Q2. A series RLC circuit with L = 15 mH, C = 3.1 F, and R = 4.7 is driven by a generator with a maximum emf of 120 V and a variable angular frequency 8700. Find out phase angle (in degrees).
