when a proton is released from rest in a room, it starts with an initital acceleration a0 towards west . When it is projected towards north with a speed v0, it moves with an initial acceleration 3a0 towards west. Find the elecrtic field and the minimum possible magnetic field in the room.
A. ma0/e east, 3ma0/ev0 down
B. ma0/e west, 2ma0/ev0 up
C. ma0/e west, 2ma0/ev0 down
D. ma0/e east, 3ma0/ev0 up
