As vector c has value on j and k axis, vector b will have values on i and j axis (We do not need on this problem)
Given vector A = i+ j+ k  Modulus of |A|  = root 3
|C| = root 2
A.B = ABcos theta =3
root3 Bcos theta =3
                         Bcos theta = root3
Similarly ABsiin theta = c = root2
Bsin theta = root2/3
tan theta =root 2 /3
therefore B = rot 11/ root3
