Concept:Transpose the given formula so that $T$ is isolated on one side.Explanation:Start with $m = N\sqrt{\frac{SL}{T}}$.Square both sides to remove the square root.This gives $m^2 = N^2 \cdot \frac{SL}{T}$.So $m^2 = \frac{N^2SL}{T}$.Multiply both sides by $T$ to move $T$ from the denominator.Then $Tm^2 = N^2SL$.Divide both sides by $m^2$ to make $T$ the subject.Therefore $T = \frac{N^2SL}{m^2}$.In the options, the variable is written as $M$ instead of $m$.So the matching answer is $\frac{N^2SL}{M^2}$.Answer:Option B: $\frac{N^2SL}{M^2}$.
