Two point charges of +30.0 μC and -9.00 μC are 20.0 cm apart, with the negative charge to the right of the positive charge. Taking to the right as being the positive x-direction, what is the electric field midway between these two charges?

A piece of wire 100 meters long has a resistance of 0.10 Ω. A current of 20 A runs through the wire, with a “voltage” at the input of 240 volts. (Note the input voltage of 240 volts is not the voltage drop…not delta(V)). What is the power delivered at the far end of the wire (or power “transmitted”)?
