Question

give two properties of electric field line

Answer 1

1.the feild lines never intersect
2. The travel frm north to south and inside the magnet they table frm south to north

Answer 2

If the electric field in a given region of space is zero, electric field lines do not exist. The tangent to a line at any point gives the direction of the electric field at the point. Also, this is the path on which a positive test charge will tend to move if free to do so.
