Three Van de Graaff generators are charged with different amounts of charge. Three locations – A, B, and C - are shown. The relative charge of each generator (expressed in terms of Q) and the relative distance of each location from the generator’s center (expressed in terms of R) are shown. Rank the three locations according to their electric field strength (E).
Tap the fields below to rank the locations in terms of their E value.
