A) 200 pm
B) \[\sqrt{\frac{3}{2}}\,pm\]
C) 142.2pm
D) \[\sqrt{2}\,pm\]
Correct Answer: A
Solution :
For bcc unit cell, \[d=\frac{\sqrt{3}}{2}\,\,\times \,\,a\] \[or\,\,a\,\,=\,\,\frac{2d}{\sqrt{3}}\,\,=\,\,\frac{2\times 173}{\sqrt{3}}\,\,\,\approx \,\,200\,pm\]You need to login to perform this action.
