 When an object such as a plastic comb is charged by rubbing it with a cloth, the net charge is typically a few microcoulombs. Part A If that charge is 3.0 μCμC , by what percentage does the mass of a 33 gg comb change during charging? Express your answer using two significant figures.

An object is charged by the transfer of electrons with the object it is rubbed. The charge on the plastic comb is The magnitude of charge on single electron is The number of electron that makes charge Q is   Mass of one electron is The mass of N electrons is   The change in mass of the comb is equal to the mass of N electrons. The percentage of the change in mass of the comb is Using 1g=10-3kg  #### Earn Coins
