An electrically neutral balloon is rubbed on cloth and becomes positively charged. what can be said about its mass:

The charged balloon’s mass will be almost equal to the original mass

Explanation:

When an electrically neutral balloon is rubbed on cloth, it losses some electron and becomes positively charged.

The balloon becomes positively charged by the removal of electrons (electrons from the cloth repels electron in the balloon).

The mass of positively charged balloon, will be equal to the original mass minus the mass of electrons removed.

Since Electrons have negligible mass, the removal of electrons from the neutral balloon will have little effect on the original mass of the balloon.

Therefore, the charged balloon’s mass will be almost equal to the original mass
