Passage VI
Quarks constitute 1 of the 3 classes of elementary particles that form all matter in the universe. Three quarks bound together form a type of particle called a baryon. A quark's effective mass (mass when bound to other quarks) is greater than its single-quark mass (mass when unbound). In addition, all quarks possess a property called spin. A quark's spin can be oriented in 1 of 2 directions, spin-up (
) or spin-down (
).
Table 1 lists the symbol, electric charge, and approximate single-quark mass for each of the 6 quarks.
Table 2 gives the symbol, mass, quark content, and quark spins for several baryons.
38. Based on Tables 1 and 2, the 
baryon has the same electric charge as a baryon containing which of the following quark combinations?
Your Answer is
Correct Answer is F
Explanation
Find Ω- in the last line of table 2, its quark content is sss, corresponding to table 1, calculate the charge level -1;
Then compare table 1 respectively Calculate the charge amount corresponding to each option, and find that only the charge amount of F option is also equal to -1
