When a proton is released from rest in a room, it starts with an initial acceleration $\displaystyle \mathrm{a}_0$ towards west. When it is projected towards north with a speed $\displaystyle v_0$ it moves with an initial acceleration $\displaystyle 3 \mathrm{a}_0$ toward west. The electric and magnetic fields in the room are :
Official answer
(2)
$\displaystyle \frac{\mathrm{ma}_0}{\mathrm{e}}$ west, $\displaystyle \frac{2 \mathrm{ma}_0}{\mathrm{e} v_0}$ down
