## Is electric field always perpendicular to equipotential surface?

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

## What is an equipotential surface Why is electric field always perpendicular to an equipotential surface?

In other terms, the potential difference between any two points in an equipotential surface is equal to zero. The electric field is always perpendicular to the surface because in the equipotential surface there is no potential difference along any direction which is parallel to the equipotential surface.

## Are electric field lines parallel or perpendicular to equipotential lines?

Equipotential lines are always perpendicular to electric field lines. The process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor is called grounding.

## Why are electric field lines perpendicular to magnetic field?

The motion of charge also generates a magnetic field which wraps around the direction of motion. Off to the side, the magnetic field is perpendicular to the distortion, and the two of them move away from the charge at a rate which is determined by how they interact with each other.

## What is the direction of electric field with respect to an equipotential surface?

Perpendicular to the equipotential surface.

## What is the direction of electric field with respect to equipotential surface for any charge distribution justify?

is equal to 0. Thus, the force acting on the point charge is perpendicular to the equipotential surface. Electric field lines give us the direction of electric force on a charge. Thus, for any charge configuration, equipotential surface through a point is normal to the electric field.

## What do you mean by equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. … In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

## What is equipotential surface Class 12?

Equipotential surface is a surface where all the points lying on the surface have the same electric potential. This means that a charge will have the same potential energy at every point on the equipotential surface.

## What is equipotential surface give an example?

a surface all of whose points have the same potential. For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.

## How are electric field lines related to equipotential surfaces?

B. Electric field lines are always perpendicular to equipotential surfaces and point toward locations of lower potential. … Electric field lines are always perpendicular to equipotential surfaces and point toward locations of lower potential.

## Do the electric field lines cross can two equipotential lines ever cross explain?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
