Question

For the dipole shown in the figure, find direction of the electric field at points on the x axis. (figure 1) horizontally to the left vertically upward vertically downward horizontally to the right Find magnitude of the electric field at points on the x axis. Express your answer in terms of the variables q,a,x and appropriate constants. What does the expression reduce to when the distance between the two charges is much less than x? Express your answer in terms of the variables q,a,x and appropriate constants.

Explanation / Answer

A: vertically downward

B:E=2KQa/((a^2+x^2)^(1.5)

C:E=2KQa/x^3
