The set containing only vector quantities is:
(A) Thermal capacity, Magnetic susceptibility and Electric charge
(B) Magnetic moment, Electric field intensity and Torque
(C) Magnetic flux, Electric potential and Force
(D) Magnetic induction, Electric capacitance and impulse
Solution
The quantities in which have both the magnitude and as well as the direction are known as the vector quantities. Here, we will check all the given options whether they are vector quantities or not.
Complete step by step answer:
Option A: Thermal capacity, Magnetic susceptibility and the Electric charge are the physical quantities which depend on the properties of matter and hence they are the scalar quantities. So, all the three sets of answers are not vectors.
Option B: Magnetic moment, Electric field Intensity and torque are physical quantities which are derived from the various types of the forces where direction of the applied force is at most important and hence, they are vector quantities. So, all the three sets of answers are vectors.
Option C: The magnetic flux is the dot product of the magnetic field. So both the Magnetic flux and electric potential are scalar quantities whereas force is the vector quantity which depends on the direction of the acceleration applied. So, all the three sets of answers are not vectors.
Option D: Magnetic Induction is the force occurring by the north –pole of the magnet and depends on the direction. Therefore it is the vector quantity. Since, the electric capacitance is the property of the material and therefore scalar quantity. Impulse is the integral of force and therefore the vector quantity. So, all the three sets of answers are not vectors.
Hence, from the given multiple choices – the option B is the correct answer.
Note: Remember the difference between the vector quantities and the scalar quantities. The quantities which have only magnitude are known as the scalar quantity. For example, mass, kilogram, length and many more. Remember the standard formula for the physical quantities which will help to distinguish the scalar and vector quantities.
