A) \[{{10}^{2}}\]
B) \[3\times {{10}^{4}}\]
C) \[{{10}^{2}}\]
D) \[{{10}^{4}}\]
Correct Answer: D
Solution :
r. m. s velocity \[=\sqrt{\frac{3P}{d}}\]Where P = pressure \[={{10}^{6}}\]and d = density = 0.03 So, r. m. s velocity \[=\sqrt{\frac{3\times {{10}^{6}}}{0.03}}\] \[=\sqrt{\frac{3\times {{10}^{6}}}{3\times {{10}^{-2}}}}\] \[=\sqrt{{{10}^{8}}}={{10}^{4}}\]You need to login to perform this action.
