(c) 12 0 dd ⋅= GG since ˆˆ ij=0 . The two vectors are perpendicular to each other. (d) 1 2 (/ 4 )( ) / 40 = G G , as in part (c). (e) 1 2 1 2 ˆ (j i)= k dd d d d d ×= × , in the + z -direction. (f) 21 2 1 1 2 ˆ (i j) = k d d d × − , in the z -direction. (g) The magnitude of the vector in (e) is . (h) The magnitude of the vector in (f) is . (i) Since 1 2 ˆ ( / 4) ( / 4)k d d G , the magnitude is /4. (j) The direction of 1 2 ˆ ( / 4) ( / 4)k d d is in the + z -direction. 56. The two vectors 1 d G and 2 d G are given by 11 2 2 j and
