Question

A neutral metallic plate is given +80 charge will its mass change if yes by how much

Answer 1

Answer:Yes

This +80 charge implies that there is removal of electrons from that object.

So, its mass changes is due to removal of 80electrons.

So its mass decreases by 80 times the mass of one electron.

Since,

mass of one electron is 9.1×10^-31 kg

So, mass of 80 electron

=80×9.1×10^-31

=7.2×10^-29 kg

So, its mass changes by 7.2×10^-29kg
