We need to apply vector math sometimes in the calculation of stability of equilibrium configurations. So the coordinate of the Force vector AB is A (2, 0, 2) and B (-2, 3.46, 3). It has a magnitude of 750N. Which is the best Cartesian representation of the vector AB?
  • a)
    -557i + 482j + 139k N
  • b)
    -557i – 482j + 139k N
  • c)
    -557i + 482j – 139k N
  • d)
    557i – 482j – 139k N
Correct answer is option 'A'. Can you explain this answer?

First try to make the unit vector of AB. Then you will get the Cartesian form of unit vector, after that just multiply 750 scalar quantity with it. Which means you are first taking out the desired direction and then multiplying the scalar to get the desired vector in desired direction.

Given Data:
Coordinates of point A: (2, 0, 2)
Coordinates of point B: (-2, 3.46, 3)
Magnitude of vector AB: 750N

Calculating Vector AB:
To find the vector AB, we subtract the coordinates of point A from the coordinates of point B.
AB = B - A
AB = (-2 - 2)i + (3.46 - 0)j + (3 - 2)k
AB = -4i + 3.46j + k

Calculating Magnitude of Vector AB:
The magnitude of a vector in 3D space is calculated using the formula:
|AB| = √(x^2 + y^2 + z^2)
|AB| = √((-4)^2 + 3.46^2 + 1^2)
|AB| = √(16 + 11.9716 + 1)
|AB| = √28.9716
|AB| ≈ 5.386

Comparing with Given Magnitude:
The given magnitude of vector AB is 750N, which does not match the calculated magnitude of approximately 5.386. Therefore, the correct representation of vector AB in Cartesian form is:
-557i + 482j + 139k N
Therefore, option A is the best Cartesian representation of the vector AB.
