Question 762: Electrostats & Capacitance

Question

Out of the following statements which is NOT the characteristics of electric lines of force?

Accepted Answer

Option A:
"Electric lines of force originate from a positively charged object and end on negatively charged object."
Ã¢ÂÂ Correct. This is a fundamental property of electric field lines.
Option B:
"The electric lines of force do not intersect each other."
Ã¢ÂÂ Correct. Field lines never cross, because at any point the electric field has a unique direction.
Option C:
"The electric lines of force pass through the conductor."
Ã¢ÂÂ Incorrect. Inside a conductor (in electrostatic equilibrium), the electric field is zero. Thus, electric field lines do
not
pass through conductorsÃ¢ÂÂthey remain perpendicular to the surface and end at the charges on the surface.
Option D:
"The electric lines of force are crowded in a region where electric intensity is large."
Ã¢ÂÂ Correct. Field line density indicates the strength of the electric field.
Ã¢ÂÂ Correct Answer:
Option C
Electric lines of force do
not
pass through a conductor in electrostatic equilibrium.

Answer

Electric lines of force originate from a positively charged object and end on negatively charged object.

Answer

The electric lines of force do not intersect each other.

Answer

The electric lines of force pass through the conductor.

Answer

The electric lines of force are crowded in a region where electric intensity is large.
