A) \[8.4\,m/{{s}^{2}}\]
B) \[9.8\,m/{{s}^{2}}\]
C) \[7.2\,m/{{s}^{2}}\]
D) \[4.2\,m/{{s}^{2}}\]
Correct Answer: A
Solution :
The value of g on the surface of the earth \[g\propto \frac{1}{{{R}^{2}}}\] At height h from the surface of the earth \[R=\frac{pV}{T}=\frac{[M{{L}^{-1}}{{T}^{-2}}][{{L}^{3}}]}{[\theta ]}\] \[=[M{{L}^{2}}{{T}^{-2}}{{\theta }^{-1}}]\] \[\Delta x=4mm=4\times {{10}^{-3}}m\] \[\Delta T={{32}^{o}}C\]
