If vec a = i + 2j+3k, vec b = i-2j+k, vec c = 4i+3j-2k and vec a + lambda vec b is perpendicular to vec c then lambda =

If the vectors vec a = i-j+2k, vec b = 2i+4j+k and vec c = lambda i + j + mu k are mutually perpendicular then (lambda, mu) =

Thescalar product of the vector hat i + hat j + hat k with a unit vector along the sum of vectors 2 hat i + 4 hat j - 5 hat k and lambda hat i + 2 hat j + 3 hat k is equal to one. Find the value of lambda .

If the vectors - 3 bar(i) + 4 bar(j) + lambda bar(k) and mu bar(i)+ 8 bar (j) + 6 bar(k) are collinear vectors, then find lambda and mu

If the points whose position vectors are -2i + 3j + 5k, i + 2j + 3k, lambda i - k are collinear, then lambda =
