Question

if for argument's sake the charge to mass ratio of an electron (e/m) was found to be 5000,000 C/Kg (C is the unit of charge) and the charge as later determined to be 400 C. what would be the weight of the electron?

if for argument's sake the charge to mass ratio of an electron (e/m) was found to be 5000,000 C/Kg (C is the unit of charge) and the charge as later determined to be 400 C. what would be the weight of the electron?

Answer:

Formula: charge to mass ratio of an electron – 5000,000 C/Kg

Proportion $\frac{5000,000\mathrm{C}}{1\mathrm{Kg}} = \frac{400\mathrm{C}}{\mathrm{X}\mathrm{Kg}}$

$$X = \frac {400\mathrm{C} \times 1\mathrm{Kg}}{5000.000\mathrm{C}}$$ $$X = 8 \times 10^{-5} \mathrm{Kg}.$$
