Answer:
Hello there!!
Answer:-
Q is positive.
Explanation:
AQ to your question,
VA - VB = 0
This happens when q>0 as Potential difference between two points in an electrostatic field is the amount of work done against the field in moving a unit +ve charge from one point to other.
=> VA > VB
And hence Q is positive.
Hope this helped you!
