What is the work done in moving a charge along an equipotential line?
What is the work done in moving a charge along an equipotential line?
Therefore, the work done in moving a charge on an equipotential surface is zero.
What is the charge on the equipotential line?
Equipotential lines depict one-dimensional regions in which the electric potential created by one or more nearby charges has a constant value. This means that if a charge is at any point on a given equipotential line, no work will be required to move it from one point to another on that same line.
How does charge move in equipotential surface?
The surface, the locus of all points at the same potential, is known as the equipotential surface. No work is required to move a charge from one point to another on the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.
When a charged particle moves along an equipotential surface the work done by the electric force is non zero?
It is said that no work is done in moving a charge on an equipotential surface. It means that no force is required to make the charge move.
Why is no work done in moving a charge along an equipotential line?
In an equipotential surface, the potential at all points is the same. So the difference in potential between two points is zero. Hence the work done to move a point from one point to another is also zero.
Why is the work done to move a charge on an equipotential surface zero?
So, in an equipotential (flat) surface, particles feel no force (the gradient is zero everywhere). No force ⟹ no acceleration but particles will continue their trajectory if they start with some initial momentum. So particles can (and do) move without work being done.
What is the formula for the equipotential line?
Equipotential lines are perpendicular to electric field lines in every case. W=−ΔPE=−qΔV=0. W=Fdcosθ=qEdcosθ=0. Note that in the above equation, E and F symbolize the magnitudes of the electric field strength and force, respectively.
What is an equipotential line example?
What is the equipotential line?
An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines.
What is the difference between equipotential lines and electric field lines?
Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. 3. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.
How do you draw an equipotential line?
The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge.
Is Earth an equipotential surface?
if there is some potential difference between two points of the conductor, then the charge will flow within the conductor to make the potential same. As we know earth is a conductor. Hence, we can say that earth is an equipotential surface.
Are equipotential lines positive or negative?
The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge.
What is the potential difference at the equipotential line?
Answer and Explanation: As the potential of all the points on equipotential line is same, therefore, the potential difference between any 2 points on the same equipotential line will be Zero. The unit vector directed along an equipotential line is .
Is a charged conductor equipotential?
The surface of a conductor is an equipotential surface as electric field inside the conductor is zero. if there is some potential difference between two point of conductor , then charge will flow within conductor to make the potential same. Was this answer helpful?
What is the line of force and equipotential?
All points on an equipotential surface have the same electric potential. And electric potential changes as you move along the field lines. Therefore, equipotential surfaces are perpendicular to electric lines of force.
