Answer 1

Answer:

1.54 x 10⁻¹¹kg

Explanation:

The charge to mass ratio is given as:

               1.044 x 10⁻⁸kg/C

 Charge on the proton  = 1.602 x 10⁻¹⁹C

 So;

    $\frac{e}{m}$   is the charge to mass ration

e is the charge

m is the mass

     

  1.044 x 10⁻⁸kg/C  = $\frac{1.602 x 10^{-19} }{m}$    

    m = $\frac{1.602 x 10^{-19} }{1.044 x 10^{-8} }$   = 1.54 x 10⁻¹¹kg
