Moving Charges and Magnetism

Question: An $\alpha - $particle travels in a circular path of radius 0.45 m in a magnetic field $B = 1.2\,Wb/{m^2}$ with a speed of $2.6 \times {10^7}\,m/\sec $. The period of revolution of the $\alpha - $particle is

1) $1.1 \times {10^{ - 5}}\,\sec $

2) $1.1 \times {10^{ - 6}}\sec $

3) $1.1 \times {10^{ - 7}}\,\sec $

4) $1.1 \times {10^{ - 8}}\,\sec $
