I have a very different theoretical physics question. Suppose we place a positive charge inside a conducting shell(not at the centre and not fixed), it induces the negative charge inside the shell. Now my doubt is by symmetry, the force on the charge is zero. But as the charge induces more negative charge on the side to which it is more close than the side which is far to it(as shown in the diagram), so the side which has more negative charge density attracts it.So force is not zero. But by shell theorem as it is perfectly spherical symmetry force is zero. So which of the above is true. If any other, why?
