Rectangular Components Representation of Vector F
In the rectangular coordinate system, any vector can be represented by its components along the x, y, and z axes. For the force vector F = Ai Bj Ck, the rectangular components representation is as follows:
Vector F = Fx Fy Fz
Explanation
- The x-component of vector F is represented by Fx, which is equal to the coefficient A of the i unit vector. The i unit vector is a vector in the x-direction with a magnitude of 1. Therefore, the x-component of vector F is A.
- Similarly, the y-component of vector F is represented by Fy, which is equal to the coefficient B of the j unit vector. The j unit vector is a vector in the y-direction with a magnitude of 1. Therefore, the y-component of vector F is B.
- Likewise, the z-component of vector F is represented by Fz, which is equal to the coefficient C of the k unit vector. The k unit vector is a vector in the z-direction with a magnitude of 1. Therefore, the z-component of vector F is C.
- Hence, the rectangular components representation of vector F is Fx Fy Fz, where Fx = A, Fy = B, and Fz = C.
Conclusion
In summary, option 'C' is the right statement for the force vector F = Ai Bj Ck. The rectangular components representation of any vector is given by its components along the x, y, and z axes. For the force vector F, its rectangular components representation is Fx Fy Fz, where Fx = A, Fy = B, and Fz = C.
