Charge Mass Relation

Description:

Whenever we say there is a negatively charged body, it implies that there is some excess electron on it. OR Whenever we say there is a positively charged body, it implies that there is some loss of electron from it.

Since, an electron is a particle and we know that every particle has a mass. So whenever electron gets transferred from one body to another, it carries its mass along with the charge and hence increases the mass of the body. Similarly the mass is decreased when electron is removed from the body.

So, there is a binding that mass of electron is always carried along with the charge of electron.

Yes, mass changes when we charge a body.

• Mass increases when electron is added to the body and the body is negatively charged.

• Mass decreases when electron is removed from a body and the body is positively charged.

1. 0 to -ve charge implies electron is added, so mass will increase.

2. 0 to +ve charge implies electron is removed, so mass will decrease. mass of electron is = 9.1 × 10^-31 Kg.
