Take a thin aluminium curtain rod with ball ends fitted for hanging the curtain. Cut out a piece of length about $20 \mathrm{~cm}$ with the ball at one end and flattened the cut end.
Take a large bottle that can hold this rod and a cork which will fit in the opening of the bottle. Fit the cork in the bottle with about $5 \mathrm{~cm}$ of the ball end projecting about the cork. Fold a small, thin aluminium foil (about $6 \mathrm{~cm}$ in length) in the middle and attach it to the flattened end of the rod by cellulose tape.
Put a paper scale inside the bottle in advance to measure the separation of leaves. The separation is a rough measure of the amount of charge on the electroscope.

Discuss the historical observation of frictional electrics.
It is now believed that protons and neutrons (which constitute nuclei of ordinary matter) are themselves built out of more elementary units called quarks. A proton and a neutron consist of three quarks each. Two types of quarks, the so called 'up' quark (denoted by $u$) of charge $+(2 / 3) e,$ and the 'down' quark (denoted by $d$) of charge $(-1 / 3) e$ together with electrons build up ordinary matter. (Quarks of other types have also been found which give rise to different unusual varieties of matter.) Suggest a possible quark composition of a proton and neutron.

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.
