Solve for e. T=e29<br><br><br> e=±3T√T<br><br> e=±3T<br><br> e=±3T√<br><br> e=±9T√

Answer:

option (3) is correct.

$e= \pm 3\sqrt{T}$

Step-by-step explanation:

Given $T=\frac{e^2}{9}$

We have to solve for e.

Consider the given statement,

$T=\frac{e^2}{9}$

Cross multiply, we get,

$\Rightarrow 9T={e^2}$

Taking square root both sides , we get,

$\Rightarrow \sqrt{9T}=e$

We know square root of 9 is 3.

$\Rightarrow \pm 3\sqrt{T}=e$

Thus, option (3) is correct.

$e= \pm 3\sqrt{T}$
