Measure circle on/off

Task:
Use the experiment to measure the ratio of the electrons charge to it's mass.

Fill the table with different acceleration voltages V_a respectively coil currents I and the radius you will see in the experiment. So you can determine the charge to mass ratio.

$V_{\text a}~ \text {in V} $	$\Rightarrow v_0~ \text {in}\frac{\text m}{\text s} $	coil current $I~\text {in A}$	$\Rightarrow B \text{ in T}$	Radius r in cm	$\frac{e}{m}=\frac{2\cdot V_{\rm{a}}}{(B\cdot r)^2}~\text{in}\frac{\text C}{\text {kg}}$
