[BHU 1995; MP PMT 1995; DPMT 1999; CPMT 2003]

Options:

A) 9 : 1

B) 3 : 1

C) 25 : 9

D) 16 : 25

Show Answer

Answer:

Correct Answer: A

Solution:

$\frac{I_{max}}{I_{min}} = {(\frac{\sqrt{\frac{I_{1}}{I_{2}}} + 1}{\sqrt{\frac{I_{1}}{I_{2}}} - 1})}^{2} = {(\frac{\sqrt{\frac{4}{1}} + 1}{\sqrt{\frac{4}{1}} - 1})}^{2} = \frac{9}{1}$
