Question

We have a hollow hemisphere of radius R open at its base. This hemisphere is on the inside of a uniform electrostatic field E and ~
parallel to the axis of the hemisphere.
Indicate which of the following is some justification singing all the answers.

a) We calculate the flow of electrostatic field, which crosses the hemisphere considering the hemisphere as a Gaussian surface.

b) The flow of electrostatic field, which crosses the hemisphere is proportional to the radius, R squared.

c) We can calculate the flow field electrost penthouse, which crosses the hemisphere.

d) If we multiply
