Why do the electrostatic field lines not form closed loop?

Explanation

### Step-by-Step Solution:

1. **Understanding Electric Field Lines**: Electric field lines are a visual representation of the electric field around charged objects. They indicate the direction of the electric field, which is defined as the force experienced by a positive test charge placed in the field.

2. **Direction of Electric Field Lines**: Electric field lines originate from positive charges and terminate at negative charges. This means that the lines always start at a point of higher electric potential (positive charge) and end at a point of lower electric potential (negative charge).

3. **Properties of Electric Field Lines**: One of the fundamental properties of electric field lines is that they cannot cross each other, and they cannot form closed loops. This is because if they were to form closed loops, it would imply that there is a point where the electric field starts and ends at the same charge, which contradicts the definition of how electric fields behave.
