Why electric field lines do not cross each other?
Electric field lines always point in one direction, at any point. When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.
When can electric field lines cross?
Field lines can never cross. Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.
Why can lines of force never cross one another select all that apply?
Lines of force represent the strength of the electric field at any given point. Visually the denser we draw the lines, the stronger the field is. … Therefore the lines representing the field cannot cross each other at any given location in space.
Why do equipotential surfaces not intersect?
They cannot intersect each other because two different equipotential surfaces have different electric potential. … Now the electric field is always perpendicular to the equipotential surface. If they are not perpendicular there will be two components which can cause charge to move along the surface.
Why electric field lines do not form closed loops?
If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. … Therefore, we say electrostatic field lines never form closed loops.
Can electric field lines cross?
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 If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
What would crossed electric field lines indicate?
Electric field lines indicate the direction of the force due to the electric field on a positive test charge. Each electric force has its own direction at each point. If two electric field lines crossed, that would indicate that a force has two directions at the point at which they cross.
Which of the following is false for electric lines of force?
They always form closed loops.
