Arrange the magnitudes of following vectors in ascending order (A) I xx j + j xx k + k xx i (B) If |a| = 2, |b| = 3, (A,b) = 45^(@) then a xx b (C ) (2i - 3j + 2k) xx (3i - j + 4k)

If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c =

If a = i- 2j + k, b = 2i + j - k, c = 4i + 4j + 3k then |(a xx b) xx c| =

The ascending order of the following (A) volume of the tertrahedron formed by 4i + 5j + k. - j + k. 3i + 9j + 4k, -4i + 4j + 4k (B) Volume of the parallelopiped with edges 2i + 3j + 4k. I + 2j - 2k, 3i - j + k (C ) |a xx (b xx c)| where a = 2i + 3j - 4k, b = i j + k, c = 4i + 2j + 3k (D) |(a xx b) xx c| where a = i - 2j + k, b = 2i + j - k, c = 4i + 2j + 3k

I : If a = i + 4j, b = 2i - 3j, c = 5i + 9j then c = 3a + b II : If a = 3i - 6j + 2k then the length of the vector is 3.

A=4i+4j-4k and B=3i+j +4k , then angle between vectors A and B is
