As we know equipotential surface means there is no potential difference that is no work is done on surface.so lines of force must intersect surface at right angles to satisfy this statement,so that net work is zero.

How are equipotentials lines oriented with respect to electric field lines?

Equipotential lines are always perpendicular to electric field lines. This is because equipotential lines represent points in a field with the same electric potential, so moving along an equipotential line does not change potential. Thus, the electric field lines, which point in the direction of the greatest change in potential, intersect equipotential lines at right angles.


Why are the equipotential lines near conductor surfaces parallel to the surface?

For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.


What are lines that intersect right angles called?

Lines that intersect right angles (ninety-degree angles) are described as perpendicular.


What angles do not intersect and are coplanar?

Angles that are separated by a distance. For example, any two angles of any polygon do not intersect and they are coplanar.


What angles intersect each other?

Angles do not normally intersect one another, although coterminus angles may be said to.


Do parallels and meridians intersect at right angles?

Yes. They intersect at 90 degree angles.
