Q1 of 26 Page 1

A point charge +Q is placed at point O as shown in the figure. Is the potential difference VA – VB positive, negative or zero?


The potential difference VA – VB is positive.


As the charge Q is positive as indicated in the question, thereby the potential difference which is equivalent to the work done in moving the charged particle from position A to B, making the work done or potential difference positive due to the positive nature of the charge.
