Question

Find the unit vector parallel to the
resultant of vectors P = 2î +3j+2k and =i+j+k

PLZ SOLVE THIS​

Answer 1

Answer:

Resultant of the vectors given is

(i-j+3k)+(2i+j-2k)+(-i-j-3k)

Which is equal to r= 2i-j-2k

Magnitude of r=|r|=√(2²+1²+2²)=3

Therefore the unit vectoe in the direction r is

(1/3)×(2i-j+2k)
