Question

Many molecular systems can be modeled as (approximate) electrical dipoles. The diagram below shows a dipole centered at the origin and along the x-axis. Point A is located at (r = 3.7L,0). (Note: The figure is not to scale!)

Given the above, for each statement below, if the statement is true, answer `T', if it is false, answer `F', and if the answer cannot be determined from the information provided, answer `C'. For example if `A' and `E' are true and there is not enough information to answer `C' and the rest are false, then answer `TFCFTF'. Note: the symbols N, S, E, and W refer to compass directions. E, for example would be to the right on your page

A) The direction of the net electric field at a point on the positive y-axis is W

B) The magnitude of the net electric field at point A is less than the magnitude of the net electric field at the origin.

C) The direction of the net electric field at a point on the negative y-axis is W

D) The direction of the net electric field at the point (-r,0) is E

E) The direction of the net electric field at A is E
