153534 An electron moves in a circular arc of radius 10 $\mathrm{m}$ at a constant speed of $2 \times 10^{7} \mathrm{~ms}^{-1}$ with its plane of motion normal to a magnetic flux density of $10^{-5} \mathrm{~T}$. What will be the value of specific charge of the electron?

153537 A proton enters into a magnetic field of induction $1.732 \mathrm{~T}$, with a velocity of $10^{7} \mathrm{~m} / \mathrm{s}$ at an angle $60^{\circ}$ to the field. The force acting on the proton is $\left(\mathrm{e}=1.6 \times 10^{-19} \mathrm{C}, \sin 60^{\circ}=\cos 30^{\circ}=\right.$ $\frac{\sqrt{3}}{2}$ )
