## Main Question or Discussion Point

Hi everyone,

I have some queries regarding the situation where a point charge is placed at a distance from an infinite conducting plane:say the plane is the xy plane and the charge is above it at distance z:

1) If the plane is at non-zero potential, is that true that the plane will not shield the electric field generated by the point charge, this is to say that electric field will be non zero for z<0? if so, is this due to the induced charges on the side opposite that facing the charge?

2) if the plane is instead grounded, the point charge is shielded (E=0 for z<0): is this because of the induced charge being discharged on the ground and hence no sources are there for generating field?

Thanks a lot!
