Question An electron moves with a velocity \( 1 \times 10^{3} \mathrm{~m} / \mathrm{s} \) in a magnetic field of induction \( 0.3 \mathrm{~T} \) at an angle \( 30^{\circ} \). If \( e / m \) of electron is \( 1.76 \times 10^{11} \mathrm{C} / \mathrm{kg} \), the radius of the path is nearly:
(A) \( 10^{-9} \mathrm{~m} \)
(B) \( 2 \times 10^{-8} \mathrm{~m} \)
(C) \( 10^{-8} \mathrm{~m} \)
(D) \( 10^{-10} \mathrm{~m} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
