Which of the following statements about the properties of the electric field produced by charged parallel plates is not correct?
A.
The electric field in the region outside the parallel plate is zero, except for the edge effects
B.
The magnitude of the electric field strength at any point between the plates, except near the edges, depends on the magnitude of the charge on each plate.
C.
The magnitude of the electric field strength at any point between the plates is directly proportional to the magnitude of the charge on each plate.
D.
The electric field is uniform everywhere in the space between the parallel plates
The diagram above illustrates a mode of vibration of a wire of length 125 cm. The speed of the waves along the wire is 120 ms-1. Use the diagram to answer questions 2 and 3.
