Question An electron is projected at an angle \( \theta \) with a uniform magnetic field. If the pitch of the helical path is equal to its radius, then the angle of projection is
 
(A) \( \tan ^{-1} \pi \)
(B) \( \tan ^{-1} 2 \pi \)
(C) \( \cot ^{-1} \pi \)
(D) \( \cot ^{-1} 2 \pi \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
