1. The problem statement, all variables and given/known data A Gaussian surface in the form of a hemisphere of radius R = 6.08 cm lies in a uniform electric field of magnitude E = 9.35 N/C. The surface encloses no net charge. At the (flat) base of the surface, the field is perpendicular to the surface and directed into the surface. What is the flux through (a) the base and (b) the curved portion of the surface? 2. Relevant equations [itex]\Phi[/itex] = EA 3. The attempt at a solution I assumed a would equal b, that is, both would be pi(.0608)^2 * 9.35, or .108 Nm^2/C. That is indeed the correct answer for b, but a is still incorrect.
