Web2) you cant reconcile the pictures because an infinite line of charge is an unphysical object. They do not exist in reality. Its no surprise that a mathematical model that includes infinite objects fails at some point.
WebExample 1.4. 1. A dipole is a distance r from an infinitely-long line of negative charge of density λ. The dipole moment p → is parallel to the line of charge. Find the magnitude of the torque on the dipole in terms of r, p →, and λ. The dipole moment is now pointing directly at the line of charge (perpendicular to it). WebA very long conducting tube (hollow cylinder) has inner radius A and outer radius b. It carries charge per unit length +α, where α is a positive constant with units of C/m. A line of charge lies along the axis of the tube. The line of charge has charge per unit length +α. (a) Calculate the electric field in terms of α and the distance r from the axis of the tube for (i) …
WebElectric Field of an Infinite Line of Charge. Find the electric field a distance above the midpoint of an infinite line of charge that carries a uniform line charge density . Strategy. This is exactly like the preceding example, except the limits of integration will be to . Solution. Again, the horizontal components cancel out, so we wind up with
