1. The problem statement, all variables and given/known data A cone is resting on a tabletop as shown in the figure with its face horizontal. A uniform electric field of magnitude 4550 N/C points vertically upward. How much electric flux passes through the sloping side surface area of the cone? 2. Relevant equations flux = ∫ E*dA 3. The attempt at a solution I'm really just confused given the geometry of the situation. In general, I understand that to find the electric flux, you choose a Gaussian surface (exploiting symmetries when possible), and the flux will be equal to the electric field times the area of the Gaussian surface, which is equal to the charge enclosed divided by ε_0. But what I'm unsure about is what kind of Gaussian surface to use here? As for finding the charge, since the electric field is uniform and vertically upward, should I treat it as a line of charge? This cone business is confusing me! Any help would be greatly appreciated. Thank you!
