Question A charge having \( \mathrm{q} / \mathrm{m} \) equal to \( 10^{8} \mathrm{C} / \mathrm{kg} \) and with velocity \( 3 \times 10^{5} \mathrm{~m} / \mathrm{s} \) enters into a uniform magnetic field \( \mathrm{B}=0.3 \) tesla at an angle \( 30^{\circ} \) with direction of field. Then radius will be
(A) \( 0.01 \mathrm{~cm} \)
(B) \( 0.5 \mathrm{~cm} \)
(C) \( 1 \mathrm{~cm} \)
(D) \( 2 \mathrm{~cm} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
