1.	A solid has a `b.c.c.` structure . If the distance of closest approach between the two atoms is `1.73 Å`. The edge length of the cell is `:`A. `sqrt(2)p m`B. `sqrt((3//2))p m`C. `200 p m`D. `142.2p m`
Answer» Correct Answer - 3 `2r=(sqrt(3)a)/(2)rArra=(2(2r))/(sqrt(3))=(2xx1.73)/(1.73)=2A=200p m`
