Answer the following questions related to the concepts of electric potential and electric potential energy:
(i) Distinguish between electric potential and electric potential energy on at least three distinct grounds.
(ii) Explain why the numerical value of electric potential at a point is independent of the magnitude of the test charge chosen, whereas the potential energy associated with that test charge depends on its magnitude.
(iii) State whether each of the following statements is true or false. Give a brief reason in each case:
(a) Electric potential at a point can be negative.
(b) The potential difference between two points in an electrostatic field depends upon the path taken between them.
