Question

Are electric field lines straight?

Answer 1

Yes, electric field lines are straight.

1. The electric field line starts from a positive charge and moves towards a negative charge.
2. From a single positive charge, the electric field starts from the charge and moves to infinity.
3. From a negative charge electric field come to charge from infinity.
4. In a uniform electric field, the field lines are straight, parallel, and uniformly spaced.
5. The electric field lines, however, can never form closed loops, as lines can never start and end on the same charge.

Hence, electric field lines are straight.
