Calculate the cyclotron radius of the electron when its velocity is

3.2 \times 10^{7} \mathrm{~m} / \mathrm{s}

(which corresponds to the velocity of an electron accelerated by the electric voltage of about

3,000 \mathrm{~V}

). Further, calculate the ratio of this cyclotron radius to the radius of the earth,

6.4 \times 10^{6} \mathrm{~m}
