Question

If ā=i+j-2k and 5 =3+2 - then find the value of vector a. vecter b​

Answer 1

Step-by-step explanation:

correct option is A=7/3 (i+j+2k)

The vector A is give as A =i+2j+2k

it's magnitude |A|=√1^2+2^2+2^2=3

unit vector along direction of A, A= A/|A|= i+2j+2k/3

Magnitude of B, |B|=√3^2+6^2+2^2=7

Thus vector c is c =|B|A

=C=7/3(i+2j+2k)
