Electric Charges and Fields. … The charge is moving continuously from point to point rather than jumping from one point to another and experiences continuous force in the electrostatic field. The force experienced or the path followed by charge cannot be discontinuous and hence the lines are not broken.
Why are electric field lines called discontinuous curves?
An electric field line is a continuous curve because a charge experiences a continuous force when placed in an electrostatic field. The charge moves endlessly and it doesn’t just shift from one point to the other. That’s why two field lines never cross each other. The electric field line does not end abruptly.
Are electric field lines discontinuous curves?
That is a field line cannot have sudden breaks.
Why is electric field discontinuous?
The magnitude of the electric field due to a charged spherical shell is zero inside it, maximum on its surface and then keeps decreasing as 1/r2. So the value of electric field does not vary smoothly from r = 0 to r = ? and thus it is discontinuous.
Why field lines Cannot be discontinuous curves draw field line picture of system of two point charges of opposite polarity?
The charge is moving continuously from point to point rather than jumping from one point to another and experiences continuous force in the electrostatic field. The force experienced or the path followed by charge cannot be discontinuous and hence the lines are not broken.
Can electric lines of force be discontinuous?
Electric lines of forces start from a positive charge and end in negative charge. … Electric lines of forces are continuous curves if there is no conductor. And the lines of forces are discontinuous for the conductor. 4.
Is electric field at a point continuous or discontinuous?
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.
When electric field line are straight and when they are curved?
When you have a combination of charges, the field line curves because the attraction or repulsion from the different charges changes at different distances from it.
Can electric field lines be broken?
That is, a field line cannot have sudden breaks.
Which of the following is discontinuous across the charged conducting sphere?
∴ Electric intensity is discontinuous across a charged conducting surface.
Which among the following electric field potential is are discontinuous across the surface of a charged conductor?
Electric field is discontinuous across the surface of charged conductor.
What is electrical discontinuity?
Discontinuous grounding commonly refers to the use of different grounds for different circuits, or the use of multiple connections to the same ground with some high impedance between them.
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.
Why the electric lines of force are not continuous?
“Every line of force in an electrostatic field originates from a positive charge at one end and terminates on a negative charge at other and they are discontinuous curves.
How does the electric field of two negative charges compare to the electric field of two positive charges?
(a) Two negative charges produce the fields shown. It is very similar to the field produced by two positive charges, except that the directions are reversed. The field is clearly weaker between the charges. The individual forces on a test charge in that region are in opposite directions.
