Question

find the unit vector perpendicular to both vector A=3i cap+j cap+2k cap & vector B=2i cap-2j cap+4k cap

Answer 1

Answer:

The required vector can be found by doing cross product of given vectors..

That is A×B.

Now for unit vector divide the (A×B) by magnitude if |A×B|

Hence unit vector is (A×B)/|A×B|.
