Question

As water is made of atoms having protons (charge +e) and electrons (charge 2:e), does the water flowing through pipe carry an electric current? Explain.​

Answer 1

Answer:

The net charge on proton is +e. This can be obtained by p=(32+32−31)e=+e 

Hence, proton has two 'up' quark and a 'down quark'.

The net charge on neutron is 0. This can be obtained by n=(32−31−31)=0

Hence, neutron has one 'up' quark and two 'down' quarks.
