Which sentence shows that maglev trains create specific challenges?
A
They go up to 600 kilometers per hour
(around 370 miles per hour).
B
Maglev trains are moved by electric
motors located in the guideway.
С
These magnets use less electricity than
conventional electromagnets, but they
must be cooled to temperatures as low
as minus 267 degrees Celsius (minus 450
degrees Fahrenheit).
D
This raises the train off the track a few
centimeters into a "floating" position.

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
