(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.
Can electric field lines be 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.
Is electric field at a point always continuous?
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.
Why electric field lines are continuous and open loop?
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.
Why electric field lines are continuous in charge free region?
The idea is that electric field lines can start on positive charges and finish on negative charges. In such a case electric field lines would be discontinuous. With no charges present the electric field lines must be continuous.
Why can’t two electric field lines cross?
Answer: Electric field does not direct in two directions that is why electric field lines never cross over each other. … 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.
Can electric field lines be broken?
That is, a field line cannot have sudden breaks.
What is not true about 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.
Is electric field continuous across the surface of conductor?
This implies that the electric field lines are 0 inside of a conductor but are perpendicular at the surface of a conductor and so, the electric field lines are discontinuous at the surface. It is possible since they are not continuous.
How does an electric field affect an electron?
The electric field points in the direction of the force that would be on a positive charge. An electron will move in the opposite direction of the electric field because of its negative charge. Therefore it will move toward the left.
Why electric field lines 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.
Why is electrostatic potential constant throughout the conductor?
As inside the conductor the electric field is zero, so no work is done against the electric field to bring a charge particle from one point to another. … Because there is no potential difference between any two points inside the conductor, the electrostatic potential is constant throughout the volume of the conductor.
Why electric field lines are always normal to the surface of conductor?
Electric field is defined as the gradient of potential and the surface of a conductor has a constant potential. Therefore, there is no field along the surface of the conductor and hence the electrostatic field at the surface of a charged conductor should be Normal to the surface at every point.
