Question

A newly discovered particle is found to have a quark composition of anti-bottom, up. What is the charge of this particle, in Coulombs?

Answer 1

Gives

Particle found quark composition

=$(\overline{B} u)$

Charge of anti bottom quark

$\overline{B}=\frac{1}{3}e$

Charge up quark

$u=\frac{2}{3}e$

quark composition net charge $=\frac{1}{3}e+\frac{2}{3}e=e$

Charge of partical $(\overline{B} u)=e=1.6\times10^{-19}C$

$q_{(\overline{B} u)}=1.6\times10^{-19}C$
