A charge Q is kept at the corner of acube. Electric flux passing through oneof those faces not touching that chargeis? |

Answer» Answer: CHARGE q is placed at the corner of a cube. What is the flux through one face of a cube? q/(24*epsilon) Imagine there were 8 CUBES and the charge was placed at the common corner. By Gauss’ law flux would be q/epsilon Since all 8 cubes are identical flux through each cube is q/(8*epsilon) Now in the cube the 3 FACES which share the corner at which cube is kept would have no flux through it (Field and area would be perpendicular so dot product is zero). In the remaining 3 faces, the flux is DISTRIBUTED evenly hence total flux = q/(24*epsilon) Explanation: plz follow me |
