Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
A line is perpendicular to another line when?
A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)
When is a line perpendicular to a plane?
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
What is the difference between a perpendicular line and a perpendicular bisector?
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
What is perpendicular line?
A sole line can't be perpendicular. To be perpendicular, a line has to meet with another line, to form right angles on either side. Perpendicular is the exact opposite of parallel. Parallel: = Perpendicular: -|
