Q.1.31- It is now established that protons and neutrons (which constitute nuclei of ordinary matter) are themselves built out of more 2. 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.
