Question

When a body is charged its mass, What then happens?

Answer 1

When 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.

Answer 2

Neutrons neither attract or repel anything. If the body is positively charged, the charged body's mass will be equal to the original mass minus the mass of electrons removed for charging. If the body is negatively charged, tge charged body mass is equal to the original mass.

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.
