Question

How are the electric field lines around a positive charge affected when a second positive charge is near it?

The field lines combine with the lines around the second positive charge.
The field lines overlap with the lines from the second positive charge.
The field lines bend toward the second positive charge.
The field lines bend away from the second positive charge.

Answer 1

The field lines bend away from the second positive charge.

Reason: field lines show the direction a positive test charge would be pushed. Like charges repel, so the net field vectors between them point outward and the lines curve away from each other (they do not cross).
