Asked in Premeth Test 20 — Vectors and Equilibrium (physics)Moderate

A unit vector is obtained by dividing the given vector by:

Correct answer: A. Its magnitude

  • A. Its magnitude
  • B. Its angle
  • C. Another vector
  • D. Ten

Explanation

A unit vector is obtained by dividing the given vector by its magnitude or length. This process is done to normalize the vector, resulting in a vector that has a magnitude of 1 while retaining the direction of the original vector.Dividing by the angle, another vector, or a numerical value like ten will not result in a unit vector as defined in vector algebra. It is essential to focus on the magnitude of the vector when seeking a unit vector.

About Vectors and Equilibrium

Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
