The mass of an electron is 9*10^-31kg. Find the charge in mass of a charged body if it loses 1 Coulomb of negative charge. Use your answer to explain why electricity was originally thought to be weight less.
1 coulomb = 6.642*10^18 elementary charges.
Everything given in question is above.
The Attempt at a Solution
Since we know that charging of a body depends upon transfer of electrons. So, if a body becomes negatively charged it will gain electrons that is its mass will increase and if a body becomes positively charged it loses electrons hence its mass will decrease. Don’t know where to start with formulas etc. help would be appreciated.
