Question

Which of the following aren't the properties of lines of force of an electric field?

• A. 1 and 2
• B. 2 and 4
• C. 1 and 3
• D. 2 and 3

Answer 1

Answer: (A)

1 and 2

1.The electric lines of force are imaginary lines the direction of filed lines for the positive charge is away from the centre and for the negative charge the field lines move towards the centre.

2. The field lines can never intersect each other because at the intersection point there can be two direction of field which is not possible.

3. The field originated from positive charge and terminate at the negative charge.

4. The lines of the force in free space is given by $E=\frac{q}{4\pi {\epsilon }_0{r}^2}$
