Question

Which statements about electric field lines are correct? Check all that apply.

They point toward a positive charge.
They point toward a negative charge.
They point away from a positive charge.
They point away from a negative charge.
They cross over one another between charges.
They never cross.

Answer 1

Correct choices:
- They point toward a negative charge.
- They point away from a positive charge.
- They never cross.

Brief reasons:
- By convention E-field lines show the direction a positive test charge would move: away from positive sources and toward negative sinks.
- Field lines cannot cross because that would imply two different field directions at the same point, which is impossible.
