An \( \alpha \)-particle travels in a circular path of radius \( 0.45 \) \( \mathrm{m} \) in a magnetic field \( B=1.2 \mathrm{~Wb} / \mathrm{m}^{2} \) with a speed of \( 2.6 \times 10^{7} \mathrm{~m} / \mathrm{s} \). The period of revolution of the \( \alpha \)-particle ishttps://bit.ly/YTAI_PWAP https://www.pw.live
