A) \[\frac{2R}{4-R}\]
B) \[\frac{4+R}{2R}\]
C) \[\frac{4-R}{2R}\]
D) \[\frac{2R}{4+R}\]
Correct Answer: C
Solution :
\[PV=nRT\] \[200\text{ }\times \text{ }10=\left( 0.5\text{ }+\text{ }x \right)\text{ }R\text{ }\times \text{ }1000\] \[0.5+x=\frac{2}{R}\] \[x\,\,=\,\,\frac{4\,\,-\,\,R}{2\,R}\] Answer should be 3 but NTA has given answer 2. Which is not correct.You need to login to perform this action.
