Question No.14-It is now believed that protons and neutrons 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 each 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.
