A cubical region of side a has its centre at the origin. It encloses three fixed point charges, –q at (0, –a/4, 0), + 3q at (0, 0, 0) and –q at (0, +a/4, 0). Choose the correct option(s):

[JEE Adv 2012 P1]

The net electric flux crossing the plane x = +a/2 is equal to the net electric flux crossing the plane x = –a/2.
The net electric flux crossing the plane y = +a/2 is more than the net electric flux crossing the plane y = –a/2.
The net electric flux crossing the entire region is q∕ε0 .
The net electric flux crossing the plane z = +a/2 is equal to the net electric flux crossing the plane z = –a/2.
