R = \(\frac{T}{(TS^2 + 1)}\)
R = \(\frac{T}{2(TS^2 - 2)}\)
R = \(\frac{T}{2(TS^2 + 1)}\)
R = \(\frac{R}{2(TS^2 + 1)}\)
Correct answer is B
S = \(\sqrt{\frac{2R + T}{2RT}}\)
Squaring both sides,
\(S^{2} = \frac{2R + T}{2RT}\)
\(S^{2} (2RT) = 2R + T\)
\(2S^{2} RT - 2R = T\)
\(R = \frac{T}{2TS^{2} - 2}\)
= \(\frac{T}{2(TS^{2} - 1)}
