Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

I think I have an easy problem for you, however I get confused by the simplicity and complexity at the same time.

Situation is like this: I have a point charge at a distance d from an infinite plate with thickness comparable to the distance d. Is there difference between the electric field op these scenarios:

1. I put the infinite plate at ground and apply a voltage on the point charge

2. I put the point charge at ground and apply a voltage from the infinite plate

Naively my response: there is not difference. But when I thought about the distribution of charge carriers in both scenarios... the ground makes it complicated where charge is in both situations.
