Moving Charges and Magnetism

Question: An electron has mass $9 \times {10^{ - 31}}\,kg$ and charge $1.6 \times {10^{ - 19}}C$ is moving with a velocity of ${10^6}\,m/s$, enters a region where magnetic field exists. If it describes a circle of radius 0.10 m, the intensity of magnetic field must be

1) $1.8 \times {10^{ - 4}}\,T$

2) $5.6 \times {10^{ - 5}}\,T$

3) $14.4 \times {10^{ - 5}}\,T$

4) $1.3 \times {10^{ - 6}}\,T$
