A pair of equal but opposite charges is glued to opposite ends of a plastic rod...
A pair of equal but opposite charges is glued to opposite ends of a plastic rod and placed in a uniform electric field in such a way that the rod makes a 45° angle with the field. The net force and torque on this combination of charges due to the field is zero because the charges balance out.

A pair of closely spaced parallel conducting plates, charged with equal and opposite electric charges, produces a uniform electric field in the region between them. In designing a cutting-edge device that will revolutionize the electronics industry, you set up such a pair of plates with a separation of 0.953 mm between them and charge them so that the direction of the electric field in their interior region is from plate A to plate B. Your idea requires that electrons, when...

Two particles have equal masses m and electric charges of equal magnitude and opposite sign (+q and –q). The particles are held at rest in uniform magnetic field with a magnitude of B. The direction of the field is perpendicular to the line connecting the charges. The particles are released simultaneously. What is the minimum initial separation L so that the particles do not collide after they are released? Neglect the magnetic fields produced by the particles themselves and the...
