Free Rectangular Components MCQs with Answers
26 Rectangular Components MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
A vector is resolved into perpendicular horizontal and vertical components using trigonometric relations, usually as Ax = A cos θ and Ay = A sin θ when θ is measured from the horizontal. Questions involve signs in different quadrants, reconstructing a resultant from components, and using components to analyse equilibrium.

- A. I quadrant
- B. II quadrant
- C. III quadrant
- D. IV quadrant
Explanation: The Cartesian plane is divided into four quadrants. In the II quadrant, vectors have a negative x-component and a positive y-component.
Correct answer: II quadrant- A. Z-axis.
- B. Vertical axis.
- C. Rotational axis.
- D. Horizontal axis.
Explanation: In a Cartesian plane, the x-axis is known as the horizontal axis because it runs horizontally from left to right.
Correct answer: Horizontal axis.- A. I quadrant
- B. II quadrant
- C. III quadrant
- D. IV quadrant
Explanation: In a Cartesian coordinate system, the quadrants are determined by the signs of the x and y coordinates.
Correct answer: III quadrant- A. Fx = 4√3 and Fy = 8
- B. Fx = 8 and Fy = 4√3
- C. Fx = 4√3 and Fy = 4
- D. Fx = 8√3 and Fy = 4
Explanation: The x and y components of a force vector can be found using trigonometric functions: the x-component is given by Fx = F cosθ, and the…
Correct answer: Fx = 4√3 and Fy = 4- A. 9
- B. 5
- C. 3
- D. 1
Explanation: To calculate the magnitude of a vector, we can use the formula:|A| = √(Ax² + Ay² + Az²Where 'A' is the vector and Ax, Ay, and Az are the…
