Read Solution (Total 4)
-
- a. 3i+2j
and
c. 2i-3j
are orthogonal pair.
as the dot product of two vectors is zero;so they are orthogonal. - 9 years agoHelpfull: Yes(19) No(1)
- a,c
(3i+2j)(2i-3j)
=3*2+(2*-3)
=6-6=0
Orthogonal - 9 years agoHelpfull: Yes(5) No(1)
- a and c are orthogonal pair because the dot product of 3i+2j and 2i-3j are zero.
- 9 years agoHelpfull: Yes(0) No(0)
- (a). and (c) are ortogonal pairs because product of these two vector is zero.
