What is baryon number and electric charge in units of e) for the three-quark combination uds?
A) 1, 0
B) 1, -1
C) 1, +1
D) 1, +2
E) None of the above.

Quizplus · Accepted Answer

The baryon number of a three-quark combination is always 1, as each quark has a baryon number of 1/3 and the combination has a total baryon number of 1. The electric charge is 0 because the u quark has a charge of +2/3, the d quark has a charge of -1/3, and the s quark has a charge of -1/3, so the total charge is (2/3) + (-1/3) + (-1/3) = 0. Therefore, the correct answer is A) 1, 0.
