1 answer:
Answer:
(192i +288j -216k) N
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

True since coulomb's law states that There is electric force between like charges or opposite charges. The negative sign only shows the nature of the force.
<h3>What is the coulombs law ?</h3>
coulombs formula is given by
Now it states that if two charged particles are separated by the distance r and having same or opposite charge will attract or repel each other.
The intensity of the force depend upon the distance and the nature of the charge.
