B I U A E E K udsu d Not made of quarks kay zero X X Find Ko on the particle chart in the meson family, so it must contain one quark and one antiquark. Its strangeness of +1 is key: that means it must contain one anti-s quark with a +1/3 charge. Since the overall charge is zero, add a down quark with its -1/3 charge. 1) No ud sud s Not made of neutron.
