A) \[M\,\,n\,{{R}^{2}}\,{{t}^{2}}\]
B) \[\frac{1}{2}M{{n}^{2}}{{R}^{2}}{{t}^{2}}\]
C) \[M\,{{n}^{2}}{{R}^{2}}t\]
D) \[M\,n\,{{R}^{2}}\,t\]
Correct Answer: C
Solution :
[c] \[\frac{{{V}^{2}}}{R}={{n}^{2}}R{{t}^{2}}\] |
\[\Rightarrow {{V}^{2}}={{n}^{2}}{{R}^{2}}{{t}^{2}}\] |
\[\Rightarrow V=nRt\] |
\[\Rightarrow \frac{dV}{dt}=nR\] |
\[P={{F}_{t}}V\] |
\[m=\frac{mdV}{dt}V\] |
\[=mnR.\,nRt\] |
\[P={{n}^{2}}{{R}^{2}}t\,m\] |
