Electric field lines do not form any closed loops. The statement is true because the electric field lines start from positive charge and end on negative charge. Since the starting and ending point of the electric field lines is different, a loop can never be closed.
Which of the following is incorrect about electric field lines?
Electric field lines represent the electric field present in a region. … Electric field lines never cross each other and point from positive toward negative charge. They do not form closed loops and always start from a positive charge and end on a negative charge. The correct answer is C.
Which of the following is true about electric field lines?
Electric field lines are continuous; they do not have a beginning or an ending. Electric field lines can never intersect. Electric field lines are close together in regions of space where the magnitude the electric field is weak and are father apart where it is strong.
Which statement about the electric field lines is correct?
(3)The electric field is directed inward for the negative charge. Therefore, the correct statements are “They point away from a positive charge” and “They never cross”.
What do you mean by electric field line?
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
What is the direction of the electric field?
Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.
What are electric field lines used for?
Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location.
Do electric field lines attract each other?
Electric field lines point away from positive charges (like charges repel) and towards negative charges (unlike charges attract). … Field lines do not touch or cross each other.
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.
Where is the electric field the strongest?
The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
What is electric field strength formula?
The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. It is denoted by ‘E’. Formula: Electric Field = F/q.
Is electric field a vector?
The Force per Charge Ratio
Electric field strength is a vector quantity; it has both magnitude and direction. The magnitude of the electric field strength is defined in terms of how it is measured.
