1.	If spheres of radius 'r' are arranged in ccp fashion (ABC ABC…) , the vertical distance between any two consecutive A layers is
Answer» `4rsqrt(2/3)` `4rsqrt(3/2)` 6 r `r sqrt6` Solution :Distance between two consecutive A LAYERS (d)=`2sqrt(2/3)a` But a=2r `therefore d=2sqrt(2/3) xx2r =4rsqrt(2/3)`
