Two resistors R1 = 2.00 Ω and  R2 = 5.00 Ω are connected across the ends of the bars to form a loop. A constant magnetic field  B = 2.90 T is directed perpendicularly into the page. An external agent pulls the rod to the left with a constant speed of  v = 7.80 m/s.  Find the following.

a) the currents in both resistors

b) the total power delivered to the resistance of the circuit

c) the magnitude of the applied force that is needed to move the rod with this constant velocity

 

 

A conducting rod of length l = 35.0 cm is free to slide on two parallel conducting bars as shown in the figure below. Two resistors R, = 2.00 N and R, = 5.00 N are
connected across the ends of the bars to form a loop. A constant magnetic field B = 2.90 T is directed perpendicularly into the page. An external agent pulls the rod to the
left with a constant speed of v = 7.80 m/s. Find the following.
