The radius of \(2^{\text {nd }}\) orbit of \(He ^{+}\)of Bohr's model is \(r_1\) and that of fourth orbit of \(Be ^{3+}\) is represented as \(r_2\). Now the ratio \(r_2 / r_1\) is \(x: 1\). The value of \(x\) is________. šŸ“²PW App Link - https://bit.ly/YTAI_PWAP šŸŒPW Website - https://www.pw.live
