is there any diff in mass of electron and proton after charging?

Question

if an object is being charged, what will happen to the mass of the object?

i guess if the object is positively charge, it lose some weight.
if it is negatively charge, it gain some weight.
is my concept correct?

Answer 1

Yes it does happen but the mass of one electron is so less that if there takes place exchage of a 10^90 electron the change in mass is so less that it is ignorable. But yes if the object itself weighs 10^-3 grams then it might make a difference.

Hope it helped.

Answer 2

Your wording in your question made it seem not logical and flawed. I think i know what you meant though....your question from what i understand is......does an object have a different mass when it has a net positive charge vs when it has a net negative charge. Technically you are correct. When an an object has a net positive charge that means it has lost one or more of electons (or negative ions). The mass of those electrons or negative ions that left the material was taken away from the total mass.

When the object has a net negative charge it has extra electrons, therefore it has increased in mass by the amount mass of the electrons or negative ions that have been attracted by the object. Hope that helped

Answer 3

i am sorry to say that your concept is flawed. In both cases the charge is a form of energy. In the case of the electron which is only a negative charge there is no other form of mass and though it is minniscule this solitary negative charge does have mass.



this is the result of Einsteins equeation E=mc^2 this means that any energy added to a body essentialls also acts as mass but that mass is likely to be very small because m=E/c^2 and c^2 is a really big number 9*10^16.



So to sum it all up adding energy or a charge to anything does increase its mass. Noting that the reason that the positve and negative cancel out on contact is that they are opposing types of energy like matter and antimatter. (which is reall and not only a star trek idea)

Answer 4

Yes, it is correct!



By adding n electrons, your charge (on an initially neutral body) will be



Q=n qe then the added mass is

m= n me



qe- charge of an electron = 1.602×10^-19 coulombs



me - mass of an electron = 9.109×10^-31 kilograms

Answer 5

yes indeed if you are refering to electrostatic phenomena..but the gained or loss weight is viciously tiny for the charged object..and it doesnt make any sense in calculations.



However the mass of electrons doesnt change at all..
