Question
A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d (see the Figure ). The inner shell has total charge +2q, and the outer shell has charge +4q.A.) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for r<a. And find the direction of the electric field for r<a
B.) Calculate the magnitude of the electric field for a<r<b. And find the direction of the electric field for a<r<b.
C.) Calculate the magnitude of the electric field for b<r<c. And find the direction of the electric field for b<r<c.
Explanation / Answer
first thing is the charge distribution concept:equal and opposite charges at opposite faces + inner surface of shell cant have any charge => +2q on outer surface of inner shell then -2qon inner surface of outer shell then +6q on outer surface of outer shell a)rd same as point charge k6q/r^2 Report Abuse
