Two oppositely-charged parallel plates are arranged as shown. [Figure 26.1] An electron is released from rest from the surface of the negatively-charged plate. The electron travels from the negatively-charged plate towards the positively-charged plate. Which graph shows how the force F on the electron varies with its distance x from the negative plate? [Figure 26.2]
AGraph A: Force F decreases as distance x increases
BGraph B: Force F increases as distance x increases
CGraph C: Force F increases linearly with distance x
DGraph D: Force F is constant with distance x
