Question

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
(a) $[\frac{ma_{0}}{e}]_{west},[\frac{2ma_{0}}{ev_{0}}]_{down}$
(b) $[\frac{ma_{0}}{e}]_{east},[\frac{3ma_{0}}{ev_{0}}]_{up}$
(c) $[\frac{ma_{0}}{e}]_{east},[\frac{3ma_{0}}{ev_{0}}]_{down}$
(d) $[\frac{ma_{0}}{e}]_{west},[\frac{2ma_{0}}{ev_{0}}]_{up}$
