Aclosed Gaussian surface consisting of a hemisphere and a circular disc of radius R, is placed in a uniform electric field, E, as shown in the figure. The circular disc makes an angle 0= 30 with the vertical. The flux of the electric field vector coming out of the curved surface of the hemisphere is (A)RE /3 (B)RE (C) TR E (D) 2 nR' E

option(b) is correct, if question is about net flux through the body. see attached phi and gamma i used as azimuthal and polar angle because theta is already a variable , Wishes.
Sayan
sir pls explain the calculation of inward flux.what is the value of sin(phi) here?

u know the formula of flux that is surface integral of E. here theta is given 30 degree than disc makes with vertical but e.f is along horizontal so we need theta that disc makes w...
