for the following two vectors find the constant 'p' such that the vectors a & b are perpendicular:
a = i + 2pj +3pk
b = i - 2j + pk
the answer is: p = 1 & p = 1/3, but how is this calculated? any help would be massively appreciated
i understand that the angle between the vectors, when perpendicular would be 90 degrees and apparently the dot product should be equal to zero, however the answer would suggest otherwise?
