When a proton is released from rest in a room, it 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 \( 3 a_{0} \) towards west. The electric and magnetic fields in the room are [NEET 2013] (a) \( \frac{m a_{0}}{e} \) east, \( \frac{3 m a_{0}}{e v_{0}} \) down (b) \( \frac{m a_{0}}{e} \) west, \( \frac{2 m a_{0}}{e v_{0}} \) up (c) \( \frac{m a_{0}}{e} \) west, \( \frac{2 m a_{0}}{e v_{0}} \) down (d) \( \frac{m a_{0}}{e} \) east, \( \frac{3 m a_{0}}{e v_{0}} \) up 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
