Uncharged spherical conducting shell

Click For Summary
SUMMARY

An uncharged spherical conducting shell surrounds a charge of -q at its center. When a charge of +3q is placed on the outer surface, the charges on the inner and outer surfaces of the shell reach static equilibrium at +q and -q, respectively. The +3q charge does not affect the total charge on the exterior but influences the distribution of charge on the shell. This conclusion is derived using Gauss's Law, which states that the electric field E is proportional to the enclosed charge q divided by the permittivity ε and the area.

PREREQUISITES

An uncharged spherical conducting shell surrounds charge -q at the center of the shell. Then a charge+ +3q is placed on the outside of the shell. When static equilibrium is reached, the charges on the inner and outer surfaces of the she are respecteively... +q,-q is the answer.

Does the +3q charge play any roll in that answer? Help. Thanks!

Do you know Gauss's Law ?
 
Yes, its E=q/[ε*area], where q is the charge enclosed.

That should give you your answer.
 
So +3q charge doesn't play any roll at all right?

That is correct, as far as the total charge on the exterior. However,the +3q does affect the distribution of that charge.
