Two point charges have a total electric potential energy of -24 J, and are separated by 29 cm. If the total charge of the two charges is 45 μC, what is the charge, in μC, on the positive one? What is the charge, in μC, on the negative one?
Levitation: The largest electric field strength you can create in air before dielectric breakdown (a spark) occurs is about 3.0 x 10°V/m. Suppose you created an electric field with this strength – pointing directly upward – between a set of parallel plates that are 9.9cm apart. You want to use this system to levitate water droplets with a mass of 1.8g. (a) How much charge would you have to put on a droplet to make it levitate? (b) Suppose that 43 charged droplets are levitating and the field strength suddenly drops by 24 percent, to about 2.3 x 106 V/m, how quickly would the droplets accelerate? E

using no mathematics, explain the physical mechanism by which bound surface charge arises in a dielectric material in an external electric field – how does it come about, what does it ‘look’ like?
