Two infinite parallel metal planes, contain electric charges with charge densities `+sigma` and `-sigma` respectively and they are separated by a small distance in air. If the permittivity of air is `epsi_(0)` then the magnitude of the field between the two planes with its direction will be

`sigma//epsi_(0)` towards the positively charged plane

`sigma//epsi_(0)` towards the negatively charged plane

`sigma//(2epsi_(0))` towards the positively charged plane

0 and towards any direction
