Answer:
Decreases fundamentally for getting positive charge and increases in case of obtaining a negative charge.
Step-by-step explanation:
As we know that the basic elemental unit of charge is an electron. All the charges are fundamentally quantized in multiples of an electron charge.
So, whenever a neutral object is charged, it either looses electron to get a positive charge or gains electron to be negatively charged and precisely electron has some mass so there is change in the mass of the object at microscopic level when it gets charged.
