A dog sleigh driver prepared for her race. her sleigh was loaded with equipment, but on snow and ice, the dogs moved the heavy sled. Each dog pulled with a force of 600 N. During the race, she came to an area of grass and dirt instead snow. The sled slowed to a stop.
The driver said, "There must be something wrong with one of the dogs. One of them is pulling with a force of less than 600 N.
How would you respond to the dog sled driver?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
