Answer:
X: positive
Y: positive
Step-by-step explanation:
The electrical field lines have a specified direction based upon the sign of the charge. The electrical field lines have a direction coming out of the charge if the sign of the charge is positive. While the electrical field lines have a direction going inside the charge if the sign of the charge of negative.
It can be clearly seen in the diagram that the electric field lines are coming out of both charges. Therefore, both the charges are positive.
Hence, the correct option is:
X: positive
Y: positive
