    The density for simple cubic lattice is : (a) \[4A/{{a}^{3}}\]                         (b) \[2A/N{{a}^{3}}\] (c) \[A/N{{a}^{3}}\]                                          (d)\[A/N{{a}^{2}}\] where A= atomic number, \[a\]= lattice parameter, N= Avogadros number

    A)  OR gate                              

    B)  AND gate

    C)  NOR gate                           

    D)  XOR gate

    Correct Answer: B

    Solution :

                    In a simple cubic lattice\[V={{a}^{3}}\] so, density \[=\frac{A/N}{V}=\frac{A}{N{{a}^{3}}}\]
