Which hydrogen-like species will have the same radius as the 1st Bohr orbit of a hydrogen atom?

Consider an electron moving in the first Bohr orbit of a He\(^+\) ion with velocity \(v_1\). If it is allowed to move in the third Bohr orbit with velocity \(v_3\), determine the correct \(v_3 : v_1\) ratio.\\
