A) 2.16\[\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) 3.62\[\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) 3.94\[\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) 4.15\[\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
[b] For fcc unit cell, \[4r=a\sqrt{2}\] \[a=\frac{4r}{\sqrt{2}}=\frac{4\times 1.28}{\sqrt{2}}\overset{\text{o}}{\mathop{\text{A}}}\,=3.62\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
