Answer :
The electric field E at the surface will be perpendicular to the surface and will be strongest where the surface is most curved.
When a charge is dumped onto a conducting surface, the charge will spread out due to repulsion forces, creating an electric field around the surface. This electric field will be perpendicular to the surface and will be strongest where the surface is most curved, following the principle of the electric field lines being closer together where the field is stronger. This leads to the correct option being that the electric field E at the surface is perpendicular to the surface and strongest where the surface is most curved, as this aligns with the principles of electric fields and conducting surfaces.
