`OA, OC, OF` are vectors from center of cube to corner of cube each one has magnitude`L`. `|OA+OC + OF| = bL`. Value of b is

A compound formed by elements X and Y has a cubic structure in which X atoms are at the corner of the cube and Y atoms are at the face centres. One atoms X is misssing from the corner. a. Calculate (i). Z_(eff') (ii). total number of the atoms in the cube, and (iii). formula of the compound. b. If alll the atoms are removed from one of the faces of the cube containing atoms at corners, as in (a) above, calculate (i) Z_(eff') (ii) total number of atoms in a cube, and (iii) formula of the compound.

A point charge q is placed at one corner of a cube of edge a. The flux through each of the cube faces is
