Hydrogen-1 ($^{1}_{1}\text{H}$) is an isotope of hydrogen. A hydrogen-1 atom contains a proton and an orbiting electron. The antiparticle version of hydrogen-1 contains an antiproton and an orbiting positron. State the charge on the positron in terms of the elementary charge $e$.
(b(ii))[1]
State the type of fundamental particle that the positron belongs to.
