Obtain a block of wood with nails through it. The nails represent uniform electric field lines. (The block of wood does not represent anything but serves to hold the nails in place.) P To the right is a two-dimensional representation of the same electric field as viewed from the side. A. Compare the magnitude of the electric field at points P and Q. Explain your reasoning. Suppose you were given a block of wood with nails representing a weaker uniform electric field than the one above. How would the two blocks differ? Explain. B. Obtain a wire loop. The loop represents the boundary of an imaginary flat surface of area A. (In order to allow the nails that represent the field to pass through the surface, you have only been given the boundary of the surface.) Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is: the maximum possible.
