A conductor with an inner cavity, like that shown in (Figure 1), carries a total charge of +4.80 nC . The charge within the cavity, insulated from the conductor, is q = -6.60 nC.
How much charge is on the inner surface of the conductor?
How much charge is on the outer surface of the conductor?
Homework Answers
Charge resides only on the outer surface of a charged conductor.
A conductor with an inner cavity, carries a total charge Q =4.80 nC
The charge within the cavity, insulated from the conductor = q =- 6.60nC .
The charge within the cavity, insulated from the conductor ,induces equal but opposite charge on the inner surface of outer charged conductor.
Induced charge on the inner surface of outer charged conductor.=qi= 6.80nC
a)= 6.60 nC charge is on the inner surface of the conductor
_____________________________________
The charge within the cavity, insulated from the conductor, induces equal charge on the outer surface of charged conductor. Induced charge on the outer surface of charged conductor.=qii= -6.60nC
Total charge on outer surface of conductor=Q qii = 4.8 -6.60 = - 1.80nC
b) -1.80nC charge is on the outer surface of the conductor
