What is false for electric lines of force?
They always form closed loops.
Which of the following statement is incorrect for electric lines of force?
(B) Electric lines of force are closed curves. It is false as it starts from positive charge and ends at negative charge. It cannot form a closed current. This statement is incorrect.
Which of the following is not true for electric field lines?
Electric field lines start from positive charge and end at negative charge. Two electric field lines can never cross each other. Electrostatic field lines do not form any closed loops. Electric field lines cannot be taken as continuous curve.
Which of the following is true about electric field lines?
Electric field lines point away from positive charges and toward negative charges. … Electric field lines are continuous; they do not have a beginning or an ending. g. At every point in space, the electric field vector at that point is perpendicular to the electric field line through that point.
Why electric lines of force are continuous?
(a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other. … Hence, two field lines never cross each other.
Why do electric lines of force not intersect?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
Which statement is wrong about lines of electric field?
Electric field lines does not forms closed loop as line can never start and end on the same charge.
Which of the statement is false for a perfect conductor?
Since the electric field out of a conductor is perpendicular to the surface. Therefore, it will not have component along the surface of the conductor. So, there will be no work done in moving the conductor along the surface.
Which of the following statement is correct the electric field at a point is?
Electric field at a point is continuous if there is no charge at that point. And the field is discontinuous if there is charge at that point. So both options (b) and (c) are correct.
Which is the following is not true about electric charge?
Answer: D is not true charge of one electron is not one coloumb. Coulomb is very big unit of charge.
Can electric field lines pass through insulator?
The answer is “Yes”. Insulators are materials that hinder the free flow of electrons from one particle of the element to another. Whereas dielectric or insulators can be polarised by the electric field. Rather electric field passes ONLY through the insulator.
Which of the following figures Cannot possibly represent electrostatic field lines?
So curve (b) cannot represent electrostatic field lines.
