A conducting bar of length \( l \) moves to the right on two frictionless rails, as shown in the figure. A uniform magnetic field directed into the page has a magnitude of \( 0.31 \, \text{T} \). Assume \( l = 32 \, \text{cm} \) and \( R = 8.8 \, \Omega \).**Diagram Explanation:**- The diagram shows a conducting bar moving to the right.- \( R \) represents a resistor connected to the rails.- \( \vec{B}_{in} \) indicates the magnetic field directed into the page, represented by crosses.- \( \vec{F}_{app} \) indicates the applied force moving the bar to the right.- The current \( i \) flows counterclockwise along the loop formed by the rails and bar.### Questions:**(a) At what constant speed should the bar move to produce an \( 8.6 \, \text{mA} \) current in the resistor?**[ ] m/sWhat is the direction of this induced current?- [ ] clockwise- [ ] counterclockwise- [ ] into the screen- [ ] out of the screen**(b) At what rate is energy delivered to the resistor?**[ ] mW**(c) Explain the origin of the energy being delivered to the resistor.**[Answer here]
