The electric potential due to an infinite line charge decreases as you move away from the charge. The formula to calculate the electric potential at a distance r from the line charge is V / (2) ln(r), where is the charge density of the line charge, is the permittivity of free space, and ln(r) is the natural logarithm of the distance r.

What are the electric field equations for different geometries?
The electric field equations for different geometries are: For a point charge: E kq/r2, where E is the electric field, k is the Coulomb's constant, q is the charge, and r is the distance from the charge. For a uniformly charged infinite line: E 2k/r, where E is the electric field, k is the Coulomb's constant, is the charge density, and r is the distance from the line. For a uniformly charged infinite plane: E /2, where E is the electric field, is the surface charge density, and is the permittivity of free space.
What is the electric field due to a line of charge?
The electric field due to a line of charge is a vector field that points radially outward from the line of charge. Its magnitude decreases as the distance from the line of charge increases.
Derive the expression for electric potential as line integral dueto charge distribution and due to adipole?
The electric potential due to a charge distribution can be obtained by integrating the electric field over the path from infinity to the point of interest. This is given by the line integral of the electric field, V = -∫ E ⋅ dl. For a dipole, the electric potential can be derived by considering the potential contributions from both the positive and negative charges of the dipole. The expression for the electric potential due to a dipole is given by V = k * p ⋅ r / r^3, where k is the Coulomb constant, p is the dipole moment, r is the position vector pointing from the charge to the observation point, and the dot product signifies the cosine of the angle between p and r.
Is the direction of the electric force on a charge is tangent to the field line?
No, the direction of the electric force on a charge is along the electric field vector and not necessarily tangent to the field line. The force on a charge will be in the same direction as the electric field if the charge is positive, and opposite if the charge is negative.
Why is the electric field of an infinite charged sheet not infinite?
This is a matter of limits. If you are measuring the electric field at a point that is a distance off of an infinite sheet of charge the direction of the electric field will be perpendicular to the sheet due to the symmetry of the situation. We can think of the radius as the distance between a point on the sheet and the normal line to the sheet that passes through the point where the electric field is being considered. If we look at the addition to the electric field from the charge on the sheet as this radius approaches infinity the component of the electric field in the direction of the net electric field will approach 0.P.S. Drawing a diagram of the situation with arrows denoting the directions of force from different parts of the sheet can be very helpful in understanding.

What is the Difference between line charge density and surface charge density?
The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.

How does moving a charge along an equipotential line affect its potential energy?
Moving a charge along an equipotential line does not affect its potential energy. This is because equipotential lines represent points of equal potential, so the potential energy of the charge remains constant along these lines.
What determines the number originating from a charge when an electric line is drawn?
The number that originates from a charge when an electric field line is drawn represents the magnitude of the charge creating the field. The field lines help us visualize the direction of the electric field and the relative strength of the field at different points around the charge. The closer the field lines are together, the stronger the electric field.
What is 'electrical potential' - 'energy difference' or 'voltage'?
Electrical potential deals with moving a charge in a direction opposite to an electric field. So what we are actually dealing with is Potential Energy. This can be calculated by the equation of PE = QEd where Q is the charge of the particle, E is the electric field and d is the distance the charged particle has been moved. The units of all this ends up being Joules (J). Now, electric potential difference is another story. This is the work per unit charge. In this case the unit will be V (volts).
Does a line have infinite length?
A line does have infinite length because it exists on an infinite plane. The only time it does not have infinite length is when it is a line segment.
How do you charge an electric shaver?
You usually charge an electric shaver by plugging it in to an electrical outlet. Some shavers run on line power and are not built to be charged; they will not work if not plugged it.
What does potential diffrence mean?
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit. Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance In electrostatics, potential difference is the line integral of the electric field from one point to another with respect to distance.
