Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )

In a thunderstorm, lightning can transfer more than 1020 electrons in a single strike. Approximating a storm cloud over the earth as a parallel plate capacitor, where the distance between the cloud and earth was 1.6 km and the cloud had a circular area over the earth with radius of 1.1 km, what was the potential difference between the earth and the cloud if the charge over this "capacitor" was from 1020 electrons? Assume that no rain has begun to...

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

Questions 11, 12, and 13
Electric Charge 10. When the electroscope is charged negatively by induction, it acquires extra electrons. From where do these extra electrons come? The extra eevons come from grounding the eiectroscope wh a positively charged o vo the result mll be a negave charge. 11. How can you tell if an electroscope is charged? 12. Can an electroscope, by itself, show whether it contains positive or negative charge? 13. In an electroscope, do the gold foil...

suppose you negatively charge a teflon rod by rubbing it with rabbit fur. which statement in the list is false? and why? a) The rod can attract small bits of paper, due to microscopic polarization of the paper by the electric field generated by the rod. b) The rabbit's fur will become positively charged. c) If the rod is brought near a metal object, the object will become macroscopically polarized, with its free electrons pulling toward the rod leaving a...
