say there is an infinite grounded conducting plane and a point charge of charge q is above it. the induced charge on the plane is -q and i know how to find this using the method of images to find the potential and then finding and integrating the charge density, but my text says that it should be intuitively clear that this induced charge must be -q. i'm just not seeing why it has to be, can anyone give me a simple explanation?(adsbygoogle = window.adsbygoogle || []).push({});

thanks.
