WebFigure 1.4.4 – Torque on a Dipole. Multiplying the forces by the moment arms, and summing, we find that the magnitude of the torque on this dipole is: (1.4.2) τ = 2 [ q E d 2 sin θ] = q d E sin θ. The magnitude of the dipole moment appears in the equation, as does the strength of the electric field, and the sine of the angle between them. WebNov 8, 2024 · Potential Energy of a Point Charge in a Field. In our brief discussion of the potential energy of dipoles in external fields in Section 1.4, we noted that an electric charge that is displaced within an electric field can have work done on it by the electric force, and this can be expressed as the negative of a change in electrical potential …

WebJan 5, 2024 · A uniform electric field exists everywhere in the x, y plane. This electric field has a magnitude of 4500 N/C and is directed in the positive x direction. A point charge -8.0 x 10-9 C is placed at the origin. Determine the magnitude of the net electric field at (a) x = -0.15 m, (b) x = +0.15 m, and (c) y = +0.15 m. Solution for Problem 18 19. WebFeb 20, 2024 · An equipotential sphere is a circle in the two-dimensional view of Figure 19.4. 1. Since the electric field lines point radially away from the charge, they are perpendicular to the equipotential lines. Figure 19.4. 1: An isolated point charge Q with its electric field lines in blue and equipotential lines in green.
