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)` `4r sqrt(3/2)` 6 r `rsqrt6` SOLUTION :Distance between two consecutive A layers (d) ` 2 sqrt(2/3)a ` Buta = 2 r. ` d = 2sqrt(2/3) XX 2r = 4r sqrt(2/3)`
