The conducting rod ab shown in (Figure 1) makes If the resistance of the circuit abcd is a constant 1.50 $2, find the direction of the force required to keep the rod frictionless contact with metal rails ca and db. The moving to the right with a constant speed of 7.60 m/s . apparatus is in a uniform magnetic field of 0.650 T , perpendicular to the plane of the figure. The force is directed to the left. No force is needed. The force is directed to the right. Submit Request Answer Part D Find the magnitude of the force mentioned in Part C. Figure
