← Two long, smooth, horizontal conducting rails are a distance l apart and are joined at one end by a capacitor of capacitance C, as shown in the figure. A uniform magnetic field B is perpendicular to the plane of the rails. A rod of mass m lies across the rails, and a constant horizontal force F pulls it along them, starting from rest. The resistance of the rod and the rails is negligible. How does the rod move?A small object stands 30 cm in front of a thin convex lens of focal length 20 cm. A plane mirror is placed 50 cm behind the lens, perpendicular to its axis, as shown in the figure. Light from the object passes through the lens, reflects from the mirror, and passes back through the lens. The final image is →
