KCET 2023 | Solid State Question 1 | Chemistry

If '$$a$$' stands for the edge length of the cubic systems. The ratio of radii in simple cubic, body centred cubic and face centred cubic unit cells is

$$1 a: \sqrt{3} a: \sqrt{2} a$$

$$\frac{1}{2} a: \frac{\sqrt{3}}{4} a: \frac{1}{2 \sqrt{2}} a$$

$$\frac{1}{2} a: \frac{\sqrt{3}}{2} a: \frac{\sqrt{2}}{2} a$$

$$\frac{1}{2} a: \sqrt{3} a: \frac{1}{\sqrt{2}} a$$
