If | vec A | =2 and | vec B| =4 , then match the relations in column I with the ange theta between vec A and vec B in column II. Column I, Column II (a) |vec A xx vec B| =0 , (i) theta =30^@ (b) | vec A xx vec B|=0 , (ii) theta =45^@ (c ) vec A xx vec B| =4 , (iii) theta =90^@ (d) | vec A xxx vec B| = 4 sqrt 2 , (iv) theta =0^@ .

Let vec(a), vec(b) and vec(c) be three vectors such that vec(a) = vec(b) xx ( vec(b) xx vec(c)) . If magnitudes of the vectors vec(a), vec(b) and vec(c) " are" sqrt(2) , 1 and 2 respectively and the angle between vec(b) and vec(c) " is " theta ( 0 lt theta lt (pi)/(2)) , then the value of 1 + tan theta is equal to :
