1. The Easter Bunny is trying new things so, instead of a basket of candy, she left you a funny bunny bar, a giant magnet, and parallel copper rails that are a distance, L = 80 cm apart, and are connected at each end by a light bulb as shown in the figure. (15 points) The Easter Bunny also left instructions on how to light the bulbs, which have resistances, R₁ = 2, and R₂ = 3. She said you needed to slide the bunny bar across the frictionless rails, perpendicular to the uniform magnetic field, B = 0.75 T, produced by the giant magnet. So that's what you did. R₁ × × × ひ R2 (a) Sketch the direction of the induced × × × current through each bulb when you pull the bar to the right as shown in the figure. (b) Start from basic equations (not memorized solutions) and derive a symbolic expression for the magnetic force on the sliding bunny bar in terms of L, R₁, R2, B, and v, as needed. (c) = 2.1 N, how fast will it be moving app If you pull the bar to the right with a constant force, F when the bulbs reach maximum (terminal) brightness?
