A bar of length L = 15 cm and resistance R = 6.002 rests on two metallic supports as shown in the figure below. The supports are connected with ideal cables to a battery with EMF = 8.0 V. The bar is in a uniform but variable magnetic field whose magnitude is slowly increased from zero. K Bar The bar jumps off the supports when B=0.20 T. What is the mass of the bar? 6.1g 03.18 037g 4.1g 024g
