two charges (+3uC on the left of the -5uC) are separated by a distance of 5um on a horizontal line. Point P is located 10um above the 3uC charges. a) Draw a sketch of the setting discussed in the question above. Make sure to label all points. b) calculate the field at point P. c) Calculate the potential at point P. d) the force on a +2uC placed at point P​

A1500 w electric heater is plugged into the outlet of a 120 v circuit that has a 20 a circuit breaker. you plug an electric hair dryer into the same outlet. the hair dryer has power settings of 600 w, 900 w , 1200 w, and 1500 w. you start with the hair dryer on the 600 w setting and increase the power setting until the circuit breaker trips. under what setting does the circuit breaker trip.
