How do you establish that matter is electrical in nature?
Matter is made of atom.The protons and electrons create attraction and repulsion forces as these atomic particles have an electric charge. Thus, it indicate that matter is electrical in nature. For example,
(i) When an ebonite rod is rubbed with a cat skin, ebonite rod gets negatively charged and cat skin positively charged.
(ii) A glass rod on rubbing with a silk cloth gets a positive charge.
(iii) A nylon comb rubbed with hair attracts bits of paper to it.
