How is the proton's +1 charge calculated using nuclear quark charges?
A) 1 quark = +1
B) 1/2 quark + 1/2 quark = +1
C) 2/3 quark + 2/3 quark + (-1/3 quark) = +1
D) 2/3 quark + 1/3 quark = +1
E) 1/2 quark + 1/2 quark = -1

Question

Quizplus · Accepted Answer

The proton is made up of three quarks: two up quarks and one down quark. The up quark has a charge of +2/3 and the down quark has a charge of -1/3. Adding these charges together (2/3 + 2/3 - 1/3), we get a total charge of +1 for the proton. Therefore, choice C is the correct answer.
