Problem 7: You are told that in a thundercloud, a 1 g raindrop can acquire a charge of 1.5 mC. Part (a) Assume that two such raindrops are separated by 4.8 cm. What is the acceleration, in meters per square second, of each raindrop away from each other? Part (b) The numbers provided seem to be reasonable - why should you not believe the source of this information? The raindrops would not stay at a constant distance from each other, so this situation would never occur. The acceleration is far too large. The acceleration is far too small. Raindrops are not this size. Part (c) Which premise or assumption is responsible for the error? The raindrop is too large. The mass is too small for a raindrop.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
