Question

find the unit vector perpendicular to the vectors

ā= 4^i-3^j+3^k
b= -2^i+^j-2^k​

Answer 1

Explanation:

dear

a vector perpendicular to the both of the given vectors can be found out by finding the cRoss products of the two vectors.

A=(3i+j+2k ) × (2i-2j+4k.) = 8i -8j -8k

unit vector =A /A| = 8i -8j -8k ) /√ (8 square +8 square +8 square ) = (i-j-k) /√3.

thanks for question ..cheers.
