A particle composed of two down quarks and one strange quark dds is a baryon with strangeness -1.Its total charge is
A)-3e.
B)-2e.
C)-1e.
D)+1e.

Question

Quizplus · Accepted Answer

Each down quark has charge -1/3e, and the strange quark has charge -1/3e. So the total charge of the particle is (-1/3e) + (-1/3e) + (-1/3e) = -1e. Therefore, the best choice for the total charge of the particle is -1e, which is option C.
