- Consider a region in free space bounded by the surfaces of an imaginary cube having sides of length \(a\) as shown in the figure. A charge \(+Q\) is placed at the centre \(O\) of the cube. \(P\) is such a point out side the cube that the line \(O P\) perpendicularly intersects the surface \(A B C D\) at \(R\) and also \(O R=R P=a / 2\). A charge \(+Q\) is placed at point \(P\) also. What is the total electric flux through the five faces of the cube other than \(A B C D ?\)
