Question

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

-(2)/(3)e
0
+e
+(2)/(3)e

Answer 1

the answer is +e, i got 100% on it for plato. I figured it out as if a quark is x so whats 2x-1x = x because x represents 1, so i guessed that e was for quarks and since it was positive it had a plus sign in front of it 

Answer 2

+ e

Step-by-step explanation:

The charge on an up quark is +2e /3

The charge on a down quark is -e/3

Charge on two up quarks + one down quark = +2e/3 + 2e/3 - e/3

= + e

The charge is + e.
