Out of the following statements which is NOT the characteristics of electric lines of force? ______.
Show Hint
Magnetic field lines CAN pass through magnetic materials (forming continuous closed loops). Electric field lines CANNOT pass through conductors (they break and terminate at the surface)!
Electric lines of force originate from a positively charged object and end on negatively charged object.
The electric lines of force do not intersect each other.
The electric lines of force pass through the conductor.
The electric lines of force are crowded in a region where electric intensity is large.
Show Solution
The Correct Option isC
Solution and Explanation
Step 1: Understanding the Concept:
Electric lines of force represent the electric field. One of the fundamental properties of electrostatic conductors is that the electric field inside a conductor in equilibrium is zero. Step 2: Formula Application:
$E_{inside} = 0$ for a conductor. Step 3: Explanation:
- (a) is true (Direction of field).
- (b) is true (Field is unique at every point).
- (c) is false because lines of force end on the surface and do not exist inside the material of the conductor.
- (d) is true (Density of lines relates to field strength). Step 4: Final Answer:
Statement (c) is NOT a characteristic.
