Point charges q1 = +12 nC and q2 = -12 nC are 0.100 m apart (Fig. 21.22). (Such pairs of point charges with equal magnitude and opposite sign are called electric dipoles.) Compute the electric field caused by q1 the field caused by q2, and the total field (a) at point (b) at point b; and (c) at point c.
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...
