Homework Statement
You have a conducting sphere that is in equilibrium, it has a cavity in it with positive charge +q. If you bring another charge +q2 near the outer edge of the conductor does the total surface charge on the wall of the cavity, q(int) change? There is an image attached that might explain the situation better.
Homework Equations
Not sure, possibly just logic
The Attempt at a Solution
The issue that I am having is when you bring q2 close to the conducting sphere, my intuition tells me that the charge on the wall of the cavity q(int) should redistribute throughout the conductor, leaving no excess charge anywhere on the conductor? However, the correct answer is the surface charge on the wall of the cavity q(int) doesn't change. Any help would be much appreciated!
Thanks
