Question
Select True or False for the following statements.
1) The total charge on the inner surface of the small shell is -6q.
2) The total charge on the outer surface of the small shell is zero.
3) The electric field in the region r > d is zero.
4) The total charge on the outer surface of the large shell is +2q.
5) The electric field in the region c < r < d is zero.
6) The total charge on the inner surface of the large shell is -6q.
7) The electric field in the region r < a is zero
(please explain! thanks!)
Explanation / Answer
Keep in mind that electric field lines start on + charges and end on - charges and there can be no field within either conductor else current would flow. 1) F no corresponding + charges for field lines 2) F all charge on inner shell will be on outer surface 3) F a Gaussian surface would enclose net charge 4) T Net charge enclosed is + 2q and all will be on the outer surface 5) T there is no field within either conductor 6) F (+2q to equalize -2q on inner shell) 7) T (a Gaussian surface would enclose no net charge)
