Q. A circuit contains six 240 ohm lamps with 60-W bulbs and a 10 ohm heater connected in parallel. the voltage across the circuit is 120 V. If the circuit has a fuse rated at 12 A, will it melt if everything is on?
Q. Two point charges are placed on the x axis as follows: Charge q1 = 4.00 {rm nC} is located at x = 0.200 {rm m}, and charge q2 = 5.00 {rm nC} is at x =-0.300;{rm m}. What are the magnitude and direction of the net force exerted by these two charges on a negative point charge q3 = -0.600 {rm nC} placed at the origin?
