Which of the following statements is not true about electric field lines?

Options

A. Electric field lines start from positive charge and end at negative charge.
B. Two electric field lines can never cross each other.
C. Electrostatic field lines do not form any closed loops.
D. Electric field lines cannot be taken as continuous curve.

Explanation

To determine which statement is not true about electric field lines, we will evaluate each of the four statements provided.

1. **Electric field lines start from positive charge and end at negative charge.**
- This statement is true. Electric field lines are drawn to represent the direction of the electric field, which originates from positive charges and terminates at negative charges.

2. **Two electric field lines never cross each other.**
- This statement is also true. If electric field lines were to cross, it would imply that at the point of intersection, there would be two different directions of the electric field, which is not possible.

3. **Electrostatic field lines do not form any closed loops.**
- This statement is true as well. Electric field lines created by static charges do not form closed loops; they extend from positive to negative charges.

4. **Electric field lines cannot be taken as continuous curves.**
- This statement is false. In regions free of charge, electric field lines can indeed be considered as continuous curves. They do not have to be broken or discontinuous, especially in charge-free regions.

Based on the evaluation of these statements, the statement that is not true about electric field lines is the fourth one.

**Final Answer: The statement that is not true about electric field lines is: "Electric field lines cannot be taken as continuous curves."**
