An infinite sheet of charge of constant surface density sigma coincides with the xy plane. what [otential for which e can be found. what are the equipotential surfacdes in this case?

For an infinitely large sheet of charge with current density σ, the electric field E everywhere except for points that lie in the x-y plane is given by:

E = σ/(2ε₀)

Any plane that is parallel to the x-y plane is an equipotential surface.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
