Hello :)(adsbygoogle = window.adsbygoogle || []).push({});

I would be very grateful if I get through with this bugging idea.

When I started reading about it, the first example was: A point charge in front of a finite plane conductor.

And I understood after some mathematical and geometrical procedure how it is okay to replace the finite plane with a charge of opposite sign.

Then I bumped into another problem:

Let us consider orthonormal system and point charge +q is placed on point (1,1) - it's image being in symmetry with respect to y-axis will be at (-1,1) and it's image abeing in symmetry with respect to x-axis will be at (1,-1). Until here I was okay, till I realized that another point charge was placed at (-1,-1). Why?

What's the whole point?

Thanks in advance.
