According to question ; #Half rod is present inside the cube and half is outside it. #we have to Find the minimum possible flux of the electric field through the entire surface of the cube. #using gauss law Charge inside the 3-d surface Divided by epsilan is the net electric flux through the 3-d surfaces. Here net charge in the cube is =q/2 so, electric flux from the cube is q/2e

what is meant by the statement, "electric field of a point charge has spherical symmetry, whereas that of an electric dipole is cylindrically symmetric"?class12

The electric field of a point charge exhibits spherical symmetry because it is radially symmetric and depends only on the distance from the charge. The electric field of a dipole exhibits cylindrical symmetry around the axis of the dipole moment, as it remains unchanged under rotations about this axis but varies with angle and distance relative to the dipole.
