Which of the following group of quantities represent the vectors
Correct answer: D. Velocity, Electric field, Momentum
- A. Acceleration, Force, Mass
- B. Mass, Displacement, Velocity
- C. Acceleration, Electric flux, Force
- D. Velocity, Electric field, Momentum
Explanation
Explanation for this question is as follows: Vector Quantity Definition The physical quantities for which both magnitude and direction are defined distinctly are known as vector quantities. For example, a boy is riding a bike with a velocity of 30 km/hr in a north-east direction. Then, as we see for defining the velocity, we need two things, i.e. the magnitude of the velocity and its direction. Therefore, it represents a vector quantity.

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.
