if `a = (i + j + k),a . b = 1` and `a ×b=j-k,` then `b` is equal to

If a=i-j-k,a*b=1" and "a times b=-j+k , then k is equal to

If a = 2i + 2j + k, a.b = 14, a xx b = 3i + j - 8k then b =

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

Let a = i- 2j + k and b = i-j+k be two vectors. If c is a vector such that b x c = b x a and c.a = 0, then c . b is equal to:

If a = 3i - 2j + k, b = -i + j + k then the unit vector parallel to the vector a + b is

Let a=2i+2j+k and b be another vector such that a*b=14" and "a times b=3i+j-8k then the vector b is equal to

If vec a = i+j+k, vec a. vec b = 1 and vec a xx vec b = j-k then vec b =

If a = 3i - 2j + k and b = i + 2j + 5k, then the unit vector along a - b is
