The diameter of the largest sphere that fis the void at the centre of cube edge of a BCC crystal of lattice parameter a, is?
a)0.293a
b)0.414a
c)0.134a
d)0.336a
1sorry I'm replying late.
here's the diagram . radius of individual sphers is r. blue thing is the one placed in the void.
hope this's fine
11sry dumble im not getting this yet can u explain a bit more in detail
another doubt does the void here denote the central atom which belongs to the BCC structure or some foriegn sphere
1void means empty space da. whether it truly does I dunno , but definitely here it denotes that the space is empty.
U know the basic diag of bcc no ?
then the place in which I've drawn the blue one is actually empty , here the blue one occupies this space . now got it ?
1diag was not to scale probably that's y u got confused . sry if it's that.
11no dumble just i dint get it whether the blue one was the original sphere present or what
but now perfectly fine
