1.	If a stands for the edge length of the cubic systems : Simple cubic, body centred cubic and face centred cubic, then the ratio of the redius of the spheres in these systems will be respectively
Answer» `1/2 a : sqrt3/4 a : 1/(2*sqrt2)a` `1/2 a: sqrt3 a: 1/sqrt2 a` `1/2a : sqrt3/2a : sqrt2/2 a ` `1A : 3A : sqrt2 a`. Solution :Ratio of radii of spheres in simple in simple cubic, bodycentred cubic and FACE centred cubic is, `a/2 : sqrt3/4a : (sqrt2a)/4 or a/2 : sqrt3/4a : a/(2sqrt2)`
