Which best explains how objects become electrically charged? A. Protons are rubbed from one object to another. B. A magnet rubbed on a rope electrically charges the object. C. Charged atoms are rubbed from one object to another. D. Electrons are transferred from one object to another.

Protons are rubbed from one object to another

Answer : The correct option is option D : Electrons are transferred from one object to another.

Explanation:

Option A is not correct because the protons are present inside the nucleus and it is very difficult to remove a proton.

Option B is not correct because it does not explain the phenomenon of how objects become electrically charged

Option C is not correct because atoms cannot be rubbed off easily. They are held together by intermolecular forces of attraction; and simple rubbing cannot separate them.

Therefore option D is the correct option.

An atom consists of a nucleus which contains positively charged protons and neutrons and negatively charged electrons revolve around the nucleus in fixed orbitals.

The electrons are held tight inside the atom by the nuclear force. The electrons which are presents in the outermost orbital are far away from the nucleus and are therefore loosely held by the nucleus. As a result, these electrons can be easily removed or transferred from the atom.

When 2 substances are rubbed together, theoutermost electrons are transferred from one substance to another substance and they become electrically charged.

The substance that loses electrons becomes positively charged and the substance that gains electrons becomes negatively charged.
