Question

find a unit vector parallel to the resultant of the vectors A = 2i -6 j - 3k and B = 4 i +3 j - k​

Answer 1

Answer:

 (6 i-3j -4k) / Root ( 61)

Explanation:

A = 2 i -  6 j - 3k

B = 4 i +  3 j -   k​

resultant = A + B

               =  6i - 3j - 4k

Mag R = Root ( 36+9+16) = root 61

Unit Vector of resultant = R / Magnitude R

so unit vector in direction of R is = ( 6i - 3j - 4k)/ Root ( 61)
