When an electrically neutral object is given a net positive charge, its mass can either increase or decrease depending on the context of charge addition. The discussion highlights that adding positive charge typically involves the addition of positively charged particles, such as protons or hydrogen nuclei. However, the mass change is not straightforward, as it can also depend on the removal of negatively charged particles, like electrons. Thus, the mass of the object may remain the same, increase, or decrease based on the specific particles involved in the charge alteration.

Then you can't really say that then can you?unseenoi said:i say that the mass decrease. but i don't know why,
