00:00Question says, by increasing the distance from the positive point charge, its potential

00:13A increases, B decreases, C remains same, D either increases or decreases.

00:24Here's electric potential near an isolated point charge is calculated by using formula

00:31V is equal to KQ upon R. So here's V is inversely proportional to the R means distance or separation.

00:51That means by increasing distance V will be decreased, by decreasing distance V will be

00:58increased.

01:01So the correct option will be B decreases.
