A) \[6.21\times ~{{10}^{-21}}J\]
B) \[8.2\times {{10}^{-21}}J\]
C) \[9\times {{10}^{-21}}J\]
D) None of these
Correct Answer: A
Solution :
\[E=\frac{3}{2}KT\] [where, K = Botzmann constant\[=1.38\times {{10}^{-23}}J/K]\] \[\therefore \] \[E=\frac{3}{2}\times 1.38\times {{10}^{-23}}\times 300\] \[=6.21\times {{10}^{-21}}J\]You need to login to perform this action.
