Surface area of hemispherical shell
WebMay 26, 2024 · We expect the surface area to be 2 π (since we're taking R = 1, and only half of the whole sphere). If we slice the shell into thin slices, one may be tempted to simply integrate 2 π y d x from 0 to 1, reasoning that we're adding up the surface areas of a bunch of rings the shell is made from. Unfortunately, this doesn't quite work. WebA hemispherical surface with radius r in a region of uniform electric field E→ has its axis aligned parallel to the direction of the field.
