Question:

When a proton is released from rest in a room, its 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 $3 \mathrm{a}_{0}$ towards west. Find the electric field and the maximum possible magnetic field in the room.

Solution:
