Two tiny objects with equal charges of 1 μC are placed at (0, 0) and (1.0 , 0). Suppose that a small test charge is placed so that it lies at (0.5,1.0). What is the electric field, in x 104 N/C, experienced by the test charge?

As shown in the figure, a battery with internal resistance r has initially no load connected across its terminals. Then the switches S1 and S2 are closed successively. The ammeter connected to the 6Ω resistor reads 1.875 A when S1 is closed, then 1.667 A when both S1 and S2 is closed. What is the internal resistance of the battery, in ohms, to two significant figures?
