Using the charges of up and down quark show that proton has +1 charge and neutron is neutral particle.

Q.No.6: - Using the charges of up and down quark show that proton has +1 charge and neutron is neutral particle.
Ans: - For proton p (uud) =2/3+2/3-1/3=+1
           For Neutron n (ddu) = -1/3-1/3+2/3=0
