A) \[\frac{\operatorname{E}}{2}\]
B) 2E
C) \[\frac{\operatorname{E}}{\sqrt{2}}\]
D) \[\sqrt{2}\]E
Correct Answer: C
Solution :
| Option [c] is correct. |
| Explanation: We know that, |
| \[{{E}_{0}}\propto \sqrt{{{P}_{a\operatorname{v}}}}\] |
| \[\frac{{{({{\operatorname{E}}_{0}})}_{1}}}{{{({{\operatorname{E}}_{0}})}_{2}}}=\sqrt{\frac{{{({{\operatorname{P}}_{a\operatorname{v}}})}_{1}}}{{{({{\operatorname{P}}_{a\operatorname{v}}})}_{2}}}}=\sqrt{\frac{100W}{50\operatorname{W}}}=\frac{\sqrt{2}}{1}\] |
| \[\therefore {{({{\operatorname{E}}_{0}})}_{2}}=\frac{{{({{\operatorname{E}}_{0}})}_{1}}}{\sqrt{2}}\] |
