1. a shark is able to detect the presence of electric fields as small as 1.0V/m. To get an idea of the magnitude of this field, suppose you have a parallel plate capacitor connected to a 1.5 V battery. How far apart must the parallel plates be to have an electric field of 1.0 pV/m between the plates?
2. Two metals spheres have charges of equal magnitude, 3.2 x 10^-14 C, but opposite sign. if the potential difference between the two spheres is 4.0 mV, what is the capacitance? (hint the plates are not parallel, but the definition of capacitance holds.)
