An electrostatic line of force is a continuous curve that is, it cannot have sudden breaks. Why is it so?

Text Solution

Verified by Experts

An electrostatic field line is the path of a positive test charge. A moving charge experiences a continuous force in an electrostatic field. So an electrostatic field line is always a continuous curve.
