Answer:

(192i +288j -216k) N

Step-by-step explanation:

The un-normalized vector BA is ...

320i +480j -360k

Then the normalized vector is ...

(8i +12j -9k)/√(8² +12² +(-9)²) = (8/17)i +(12/17)j -(9/17)k

The cable tension multiplies this to give the components of cable tension:

(408 N)((8/17)i +(12/17)j -(9/17)k) = (192i +288j -216k) N
