Question
PLEASE HELP!!!!
A long conducting circular rod is inside a long conducting square enclosure.
The rod is maintained at a potential of -5000 volts with respect to the square which is grounded (V=0). The contour lines are equipotentials with V = -4000, -3000, -2000, and -1000 volts.
Select a response for each statement below. (Use 'N', North, towards top of page (+y dir), and 'E', East, to the right (+x dir), 'NE' for in between 'N' and 'E', etc.)
The direction of the force on a small (+) charge at 2 is ....
The direction of the E-field at 9 is ....
The magnitude of the E-field at 4 is very small (~ zero).
The direction of the force on a small (-) charge at 1 is ....
The x-component of the E-field at 1 is zero.
The y-component of the E-field at 6 is negative.
The magnitude of the E-field at 6 is greater than that at 8

1. False. The E field is directed NW so the y-component is positive.
2. N. Straight up.
3. S. Straight down.
4. SW (at point 5)
5. False. The equipotentials are closer together at point 7 so the voltage change per meter is greater there.
6. True. The field is pointed directly in the positive x direction there.
7. True, E fields inside a conductor are zero.
