When a proton is released from rest in a room, it starts with an initial acceleration a0 towards west. When it is projected towards north with a speed v0 it moves with an initial acceleration 3a0 towards west. The electric and magnetic fields in the room are respectively
-
-
ma0 west, 2ma0 down e ev0 -
ma0 east, 3ma0 up e ev0 -
ma0 east, 3ma0 down e ev0 -
ma0 west, 2ma0 up e ev0

Correct Option: A
When moves with an acceleration a0 towards west, electric field
| E = | = | (west) | ||
| q | c |
When moves with an acceleration 3a0 towards east, magnetic field
| B = | (downward) | |
| cv0 |
