Frequent question: Which of the following is incorrect about electric field lines electric field?

Which of the following is incorrect about electric field lines?

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.

What is true about electric field lines?

Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.

Which of the following do electric field lines show?

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.

Which of the following is false for electric lines of force?

They always form closed loops.

Which of the following is correct about electrostatic field?

An electric field will be continuous because of any charge, if in the medium there is no other charge available. If there is a particular charge at a point under the consideration then, it will be discontinuous. Hence, the correct option is (b). Electric field refers to the per unit charge of electric force.

Do electric field lines intersect?

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 If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

Can the electric field be negative?

An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge. … So even if the charge is negative in nature, its magnitude will also be positive and therefore, an electric field can never be negative.

What are electric field lines and what are their properties?

Properties of Electric Field Lines. The field lines never intersect each other. The field lines are perpendicular to the surface of the charge. The magnitude of charge and the number of field lines, both are proportional to each other.

Why electric field lines do not pass through conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.

How does electric field related to electric field lines?

The strength of the field is proportional to the closeness of the field lines—more precisely, it is proportional to the number of lines per unit area perpendicular to the lines. The direction of the electric field is tangent to the field line at any point in space. Field lines can never cross.

What do field lines indicate?

An electric field can be visualized by drawing field lines, which indicate both the magnitude and direction of the field. Field lines start on positive charges and end on negative charges. The direction of the field line at a point is the direction of the field at that point.

Why electric field lines Cannot 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 curve?

This means that the overlapping curved field lines will average out as a straight field line, through the middle of the point-charge pairs. The outermost edges of the electric field, on the other hand, will have nothing to interfere with, and remain curved.

Which option is incorrect for electrostatic field?

Electric field lines does not forms closed loop as line can never start and end on the same charge.

Are electric field lines continuous?

Yes, the electrostatic field line is a continuous curve because a unit charge always experiences a continuous force when it is placed in an electrostatic field. The unit charge is the charge that passes through the cross-section of an electric conductor that carries one ampere of current in one second.
