(a) What is the electric field at x = 0.5 cm? Positive values represent electric fields in the +x direction.
V/m
(b) What is the electric field at x = 2.5 cm?
V/m
(c) What is the electric field at x = 3.5 cm?
V/m
Now consider the figure to represent the electric field instead of potential, with each vertical division on the graph equal to 30 N/C.
(d) What is the potential difference V,-V2, the difference in potential between x = 2 cm and x = 3 cm?
V
(e) What is the potential difference V-V,?
V
