Why does positive charge attracts negative charge?

 What is charge ?

All physical objects are made up of atoms. Inside an atom there are protons, electrons and neutrons. The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral.

Therefore, all things are made up of charges. Opposite charges attract each other (negative positive or positive negative). Like charges repel each other (positive positive or negative negative).

Why does positive charge attracts negative charge? 

It is the tendancy of every body to have minimum electrical potential  i.e .to obtain   zero potential .  A positive  charge means a deficit of electrons while the negative charge indicates excess of electrons . Consequently, the positive and negative charges attract each other to have minimum electrical potential. 

I hope this helps you. Thank you ❤️.
