Question 9
Scalars and VectorsWhich of the following consists entirely of vector quantities?
- A.Velocity, magnetic flux and reaction
- B.Tension, magnetic flux and mass
- C.Displacement, impulse and power
- D.Work, pressure and moment.
Show the answer and explanation
Answer: A (Velocity, magnetic flux and reaction)
Explanation
Velocity and reaction are vectors, and the magnetic field (flux) is treated here as a vector. Each other option contains a clear scalar: mass, power or work.
