A hollow ball with radius R = 2 cm has a charge of -4 nC spread uniformly over its surface (see the figure).
A hollow ball with radius R = 2 cm has a charge of -4 nC spread uniformly over its surface (see the figure). The center of the ball is at P1 = <-4, 0, 0> cm. A point charge of 5 nC is located at P3 =<6, 0, 0>cm. (The diagram below is not drawn exactly to scale.) What is the...

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...
