If a given particle has two up quarks and one down quark, what charge will it have?

a. - 2/3 E

b. 0

c. + E

d. + 2/3 E

Each up quark has a charge of + 2/3.

Each down quark has a charge of - 1/3.

The sum of the charges of quarks determine the particle's electrical charge.

In this case:

2 (+2/3) + 1 (-1/3) = particle charge

4/3 - 1/3 = particle charge

Particle Charge = + 1 E

Answer is C) + E
