WebA +8.75-mC point charge is glued down on a horizontal frictionless table. It is tied to a -6.50-mC point charge by a light, nonconducting 2.50-cm wire. A uniform electric field of magnitude 1.85 * 10^8 N/C is directed parallel to the wire, as shown in Fig. E21.34. (a) Find the tension in the wire. WebA charge q is uniformly distributed on a thin rod of mass m and length I that stays at rest in free space. Two regions of uniform electric field of intensity E are created on both sides of the rod as shown in the figure. In the region of width L where the rod is initially placed, there is no electric field. garmothe https://veedubproductions.com

WebFig. 26–2. A charge moves on an arbitrary trajectory. The potentials at (x, y, z) at the time t are determined by the position P ′ and velocity v ′ at the retarded time t − r ′ / c. They are conveniently expressed in terms of the coordinates from the “projected” position Pproj. (The actual position at t is P .) WebElectric potential of a point charge is V = kQ/r V = k Q / r. Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.
