State the characteristics of electric lines of force. |
|
Answer» 1. The lines of force originate from a positively charged object and end on a negatively charged object. 2. The lines of force neither intersect nor meet each other, as it will mean that electric field has two directions at a single point. 3. The lines of force leave or terminate on a conductor normally. 4. The lines of force do not pass through conductor i.e., electric field inside a conductor is always zero, but they pass through insulators. 5. Magnitude of the electric field intensity is proportional to the number of lines of force per unit area of the surface held perpendicular to the field. 6. Electric lines of force are crowded in a region where electric intensity is large. 7. Electric lines of force are widely separated from each other in a region where electric intensity is small. 8. The lines of force of an uniform electric field are parallel to each other and are equally spaced. |
