a long glass filament carries a charge density = -2.7nC/m. what is the magnitude of the electric field 0.67 mm from the filament?
A linear charge distribution is a type of electric charge distribution in which the charge is spread out in a straight line. This means that the charge density is constant along the line and the magnitude of the charge decreases as you move further away from the line.
A point charge is a single charge located at a specific point in space, while a linear charge distribution is a continuous distribution of charge along a line. This means that the electric field produced by a linear charge distribution will vary depending on the distance from the line, while the electric field of a point charge will be the same at all points in space.
The electric field at a point on the perpendicular bisector of a linear charge distribution can be calculated using the equation E = (λ/2πε0r), where λ is the linear charge density, ε0 is the permittivity of free space, and r is the distance from the charge distribution to the point.
To calculate the electric potential at a point due to a linear charge distribution, you can use the equation V = (λ/2πε0) ln(r/r0), where V is the potential at the point, λ is the linear charge density, ε0 is the permittivity of free space, r is the distance from the charge distribution to the point, and r0 is a reference distance.
Yes, a linear charge distribution can have a negative charge. The charge density, λ, can be positive or negative, depending on the direction of the charge along the line. A negative charge density would result in a negative electric field and potential, while a positive charge density would result in a positive electric field and potential.
