What is the flux through each face of a cube when a point charge q is placed at one of the vertices of the cube of edge length a? |
(1/8)q/ε0 (1/24)q/ε0 (1/16)q/ε0 (1/4)q/ε0 |
(1/24)q/ε0 |
Flux through cube due to charge at corners will be q/8ε0. Cube has 6 faces with 3 symmetrical and 3 having zero flux (as field will be parallel to them). As 8 X 3=24, so q/24ε0 |
