## Why electric field lines do not pass through conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.

## Why two electric lines of force passes normally from a conductor?

They start from a positive charge and end on a negative charge. A tangent drawn to a line of force at any point shows the direction of the electric field at that point. Two lines of force never intersect each other. … Lines of force do not pass through the conductor.

## Why are electric field lines perpendicular to the surface of a conductor Class 12?

So that the electrostatic field inside the conductor is zero. In the static situation, no excess charges will be present inside the conductor. … To get equipotential or constant potential throughout the surface, electrostatic field lines have to be perpendicular to the segments of the conductor.

## Why do electric field lines not cross through hollow conductors?

For a charged hollow conductor, since the entire surface of the conductor has the same charge on it, no electric field line can originate from one point on the surface and end on another point on the surface as electric field lines must originate from a positive charge and end on a negative charge.

## Why do electric lines of force pass through insulators?

The answer is “Yes”. Insulators are materials that hinder the free flow of electrons from one particle of the element to another. Whereas dielectric or insulators can be polarised by the electric field. Rather electric field passes ONLY through the insulator.

## Is it possible for lines of force to cross one another near the conductor?

Lines of force start from the negative charges and stop at the positive charges. … It is possible for lines of force to cross one another near a conductor.

## Is the electric field always perpendicular to the surface?

Equipotential surfaces have equal potentials everywhere on them. … These equipotential surfaces are always perpendicular to the electric field direction, at every point.

## When the electric field vector is perpendicular to the surface?

If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.
