Question

A hemisphere body of radius $R$ is placed in a uniform electric field $E$. What is the flux linked with the curved surface if the field is parallel to the base?

Answer 1

As the charge enclosed in the hemisphere is zero, the net flux with the closed body is zero.
As the field is parallel to the base, the flux linked with the base is zero.
Now, flux linked with base + flux linked with curved surface = $0$
Therefore, flux linked with the curved surface = $0$
