Answer:
The charge of the particle is 0.
Explanation:
A quark is an elementary particle of matter. Quarks combine to form Hadrons.
Quarks have fractional charges.
Up, charm and top quark has [tex]+\frac{2}{3}[/tex] charge.
Down, strange and bottom has [tex]-\frac{1}{3}[/tex] charge.
A particle which has two down quarks and one up quark will have net charge:
[tex]2 \times (-\frac{1}{3})+1(+\frac{2}{3}) = 0 [/tex]
Thus, the charge of the particle would be 0. It would be a neutral particle.
Neutron is composed of two down quarks and one up quark. It is a neutral particle.
