Q2 of 37 Page 19

Which one of the following statements is true?

We know scalar quantities like the energy of an electron can take a negative value. Also, we have an electric charge which is a scalar quantity and can be negative or positive in nature. Also in some cases where inelastic collision is happening energy is not always conserved. Electric Potential is scalar in nature but varies from one point to another in space.


But, it is always true that scalar quantity has the same value irrespective of from where we observing.
