Topic: Electric Flux 1. Find the magnitude of the electric flux through the top side of the cube which is 0.5 m when placed in a horizontal uniform electric field of 8.ON/C directed to the right. 2. A flat surface of an area of 1.25 m is rotated through a uniform horizontal electric field of 5.0 N/C. What is the electric flux if the surface is (a) parallel and (b) perpendicular to the electric field
