# (a) Show than all combinations of three quarks produce integral changes. Thus baryons must have integral charge.(b) Show than all combinations at a quark and an antiquark produce only integral charges. Thus mesons must have integral change.

To determine

(a)

To show that all combinations of three quarks produce integral charges and hence baryons

must have integral charges.

Explanation

Introduction:

Quarks are fundamental particles and baryons are combination of three quarks.

The six quarks and its antiquarks have the following charges. They do not have integral

charges.

To determine

(b)

To show that the combinations of a quark and an antiquark produce integral charges and

hence mesons must have integral charges.
