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 acceleration `3a_(0)` towards west. The electric and magnetic fields in the room are

`(ma_(0))/e` west, `(2ma_(0))/(ev_(0))` down

`(ma_(0))/e` east, `(3ma_(0))/(ev_(0))` up

`(ma_(0))/e` east, `(3ma_(0))/(ev_(0))` down

`(ma_(0))/e` west `(2ma_(0))/(ev_(0))` up
