4. A conducting bar can slide freely over two conducting rails as shown in Fig. 6-4 (page 237) with h=6cm. Calculate the current flowing in R a) If the bar is stationed at x=8cm and B = 8 cos(10³t)â₂mWb/m²; b) if the bar slides at a velocity = 15â, m/s and B=8a₂mWb/m²; c) if the bar slides at a velocity = 15â, m/s and B=8 cos(10³t-x)â₂mWb/m².
