A charge q sits at the back corner of a cube as shown in the figure. The electric flux through the shaded surface is (A) q/6E (B) q/12E% (C)q/E (D) q/24E,
correct option is d, assume a big cube which is made of 8small cubes so that this charge lie inside the cube.. then the flux from one face of one cube is 1/6*1/4*epilson.
