How are edge length 'a' of the unit cell and radius ' rr ' of the sphere related to each other in ccp structure? (Choose correct option for your answer.)How are edge length 'a' of the unit cell and radius ' r ' of the sphere related to each other in ccp structure? (Choose

Options

  1. Aa=4r/3a=4 r / \sqrt{3}
  2. Ba=22ra=2 \sqrt{2} r
  3. Ca=2ra=2 r
  4. Da=r/22a=r / 2 \sqrt{2}

Correct answer

B. a=22ra=2 \sqrt{2} r

Step-by-step solution

For a ccp structure, How are edge length 'a' of the unit cell and radius ' r ' of the sphere related to each other in ccp structure? (Choose 4r=a24 r=a \sqrt{2} ∴a=4r2\therefore a=\frac{4 r}{\sqrt{2}} a=22ra=2 \sqrt{2} r
