Answer:
option (3) is correct.
[tex]e= \pm 3\sqrt{T}[/tex]
Step-by-step explanation:
Given [tex]T=\frac{e^2}{9}[/tex]
We have to solve for e.
Consider the given statement,
[tex]T=\frac{e^2}{9}[/tex]
Cross multiply, we get,
[tex]\Rightarrow 9T={e^2}[/tex]
Taking square root both sides , we get,
[tex]\Rightarrow \sqrt{9T}=e[/tex]
We know square root of 9 is 3.
[tex]\Rightarrow \pm 3\sqrt{T}=e[/tex]
Thus, option (3) is correct.
[tex]e= \pm 3\sqrt{T}[/tex]
