If vectors

\bar A = 2i + 3j + Pk

and

\bar B = 3\bar i - 8\bar j + 2\bar k

are perpendicular to each other. Then value of

P

View answer and explanation

Correct option: D

If vectors

\bar A = 2i + 3j + Pk

and

\bar B = 3\bar i - 8\bar j + 2\bar k

are perpendicular to each other, then the value of

P

is 9 because their dot product must be zero.
