The number of vectors of unit length perpendicular to vectors a=i^+j^ and b=j^+k^ is _________________.

Open in App
Solution

The unit vector perpendicular to a and b is given by ±a×ba×b

for a=i^+j^ and b=j^+k^a×b=i^j^k^110011=i^1-0-j^1-0+k^1-0
a×b=i^-j^+k^i.e. a×b=1+1+1=3 number of unit vectors perpendicular to a and b is two i.e ±i^-j^+k^3
