Three point charges are placed on the x-axis. A charge of +2.0 ?C is placed at the origin, -2.0 ?C to the right at x = 50 cm, and +4.0 ?C at the 100 cm mark

What are the magnitude and direction of the electrostatic force that acts on the charge at the origin? (k = 1/4??0 =
8.99 × 109 N ? m2/C2)
What will be an ideal response?


Answer: 0.072 N, toward the right

Appliances in the USA are designed to work on 110-120 V, whereas appliances in Europe operate on 220-240 V. What would happen if you tried to use a European electric shaver in this country?

A) It would probably work as well as it does in Europe, since it is the power rating, not the voltage rating, that matters. B) It would probably work as well as it does in Europe, since it is the current rating, not the voltage rating, that matters. C) It would barely work (or maybe not work at all), since the voltage here is too low to push enough current through the device. D) It would probably overheat and burn up before very long. E) This question cannot be answered without knowing the frequency used in Europe and in the USA, since this is the parameter that matters most in any electrical device that operates on alternating current.
