If `bara` = mi + 2j - 3k and `barb` = 3i - 2j + nk are collinear, then (m, n) `equiv`

If bara = -3i + nj + 4k and barb = - 2i + 4j + pk are collinear, then

if a = 3i + 2j + k, b = 6i + mj + nk and a, b are collinear, then m, n are

If vectors i + j + k,i - j+k and 2i + 3j + mk are coplanar, then m =

If A = i + 2j + 3k, B = 2i + 4j + 7k and C = 2i + 3j + 5k are collinear, then the ratio in which B divides bar(AC) is

If bara = 2i + 3j - k , barb = - i + 2 j - 4k and barc = i + j + k . then (a xx b) · ( a xx c)

If vectors 2i - j + k, i + 2j - 3k and 3i + mj + 5k are coplanar, then m is a root of the equation

If bara = i+ 2j - 3k and barb = 3i,- j + 2k , then show that bara+barb and barb-barb are perpendicular to each other.

If bara = i + 5k, barb = 2i + 3k, barc = 4i - j + 2k and bard = i-j , then (barc - bara)·(barb xx bard) =

If 3i-2j+5k and-2i+pj-qk are collinear vectors, then
