03 - Written response question on Circuits a) What is the magnitude of the electric eld at 1.20 m distance from a point charge of 4.00 110? b) Acharge [11 = 9.00 110 is located at the origin of the xaxis. Aseoond charge (12 = 15.00 110 is also on the xaxis 4.00 rn from the origin in the positive x direction. At what point on the xaxis is the resultant electn'c eld zero?I in the circuit below, calculate: c) the current owing from the voltage source. d) the potential dierenoe across the 1.00 0 e) the current owing through the 2.00 O resistor
