normal lines or normals
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.
Perpendicular lines meet at right angles
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
If two lines intersect at right angles then they are perpendicular!

Perpendicular lines meet at right angles
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
Perpendicular lines form right angles when they intersect.
straight up or pointing to the zenith or in a direction at right angles to the surface of the earth
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
two lines that are perpendicular form right angles
Perpendicular lines form right angles at their intersections.
Perpendicular lines intersect to form right angles
If two lines intersect at right angles then they are perpendicular!
