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.
How do you relate parallel and perpendicular lines to the real world?
If you are sitting in a room, the ceiling and the floor are parallel to each other. The walls are perpendicular to the floor and to the ceiling. So any line on these surfaces will be parallel to or perpendicular to any line on the other surface. And if they were not, the building could be quite unstable.
What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal
A line perpendicular to a surface?
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
What is the name of the line drawn perpendicular to the surface where light ray strikes?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
What is the name of the line drawn perpendicular to the surface where a light ray strike?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
What is the name of the line drawn perpendicular to the surface where light rays strike?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
The angle of incidence is the angle between the incident ray and the line to the surface?
Line perpendicular to the surface.
What is a definition of Perpendicular?
Perpendicular is a line drawn over a surface at an angle of 90 degrees.
What is a line perpendicular to a reflecting surface called?
a tangent
What is the line perpendicular surface at the point is incidence?
yes
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.
When does the shadow of an object short?
When the line from the light source to the surface on which the shadow falls is perpendicular to that surface.
What is the name of the line drawn perpendiculars to the surface where the light rays strikes?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
