153558 An electron having mass $9.1 \times 10^{-31} \mathrm{~kg}$. charges $1.6 \times 10^{-19} \mathrm{C}$ and moving with the velocity of $10^{6}$ $\mathrm{m} / \mathrm{s}$ enters in region where magnetic field exists. If it describes a circle of radius $0.2 \mathrm{~m}$ then the intensity of magnetic field must be $\times 10^{-5} \mathrm{~T}$.
