WebOct 16, 2024 · The potential of a hemisphere at the centre with constant surface charge density σ is given by σ R 2 ϵ where R is the radius of the hemisphere. The magnitude of the electric field for the same configuration is given by − σ 4 ϵ. I've got the potential by doing a surface integral and the field by integrating rings that make the hemisphere.
