Can you determine the standard value of specific charge by simply using the accepted values for the charge of an electron and the accepted values for the mass of an electron (e/m)?

Okay. Can I substitute the inverse of the slope 1/(0.005) into the equation (e/m)=2V/(r^2 *B^2). Doing this I get (e/m)= 400/(B^2). I can calculate B^2 and solve. Does this seem reasonable?

A constand current of 1A is flowing through the Helmholtz coils. When the voltage is altered the radius of the deflection beam changes accordingly. The trend line analysis of radius vs. voltage graphs give an equation of the form y=0.005x+25. (Hint: graph is plotted by considering r^2 (m^2) on...
