The radius of the largest sphere which fits properly at the centre of the edge of a body centred cubic unit cell is: (Edge length is represented by ‘a’)

Question

Accepted Answer

Correct answer: D. (d) For BCC ⇒R= 3a4 ∴ Empty space at edge =a-2R=a- 3a2= diameter of sphere. ∴r_ sphere= a- 3a22= ( 2- 34 )a=0.067a
