When a proton is released from rest in a room, it starts with an initial acceleration `a_(0)` towards west. When it is projected towards north with a speed `v_(0)` it moves with an initial accelaration `3a_(0)` towards west. The electric and the maximum possible magnetic field in the room   (i) `(ma_(0))/(e)`, towards west   (ii) `(2 ma_(0))/(ev_(0))`, downward   (iii) `(ma_(0))/(e)`, towards east   (iv) `(2ma_(0))/(ev_(0))`, upward
