5. Hummingbirds can pick up static charge as they fly either from the air or from interactions with plants. A possible value is +250 pC. a. Given this charge, did the bird gain positive charge or lose negative charge? Explain. b. If we model the hummingbird as a sphere with the above net charge attained from the air with a radius of 2.9 cm, what is the electric potential or "voltage" at the bird and 5 cm away from the bird? c. If we model the bird (charged through interactions with plants) as one side of a capacitor with the earth as the other side with the opposite charge, and the capacitance is 1.3 pF, what is the potential difference between the bird and the earth? (parts band c are independent questions.)

Your friend gets really excited by the idea of making a lightning rod or maybe just a sparking toy by connecting two spheres as shown in Figure 7.39, and making R2so small that the electric field is greater than the dielectric strength of air, just from the usual 150 V/m electric field near the surface of the Earth. If R1is 10 cm. how small does R2to be, and does this seem practical? (Hint: recall the calculation for electric field at the surface of a conductor from Gauss's Law.)
