(i) `q` is positive and `Delta` is along the line joining the charges
(ii) `q` is positive and `Delta` is perpendicular to the line joining the charges
(iii) `q` is negative and `Delta` is perpendicular to the line joining the charges
(iv) `q` is positive and `Delta` is along the line joining the charges

A

q is positive and the given displacement is along line joining the charges.
