A rod of mass 0.720 kg and radius 6 cm rests on two parallel rails that are `d=12 cm` apart and length of rails is `L=49 cm.` The rod carried a current of `I=48 A` Fig. and rolls along the rails without slipping. A uniform magnetic field of magnetude 0.240 T is directed perpendicular to the rod and the rails. If it starts from rest, what is the speed of the rod as it leaves the rails?

A rod of mass m and radius R rest on two parallel rails that are distance l apart and have a length L . The rod carries a current I ( in the direction shown ) and rolls along the rails without slipping. A uniform magnetic field B is directed perpendicular to the rod and the rails. If it starts from rest, wat is the speed of the rod as it leaves the rails ?

Two parallel rails with negligible resistance are 10.0 cm apart. The are connected by a 5.0Omega resistor. The circuit also contains two metal rods having resistances of 10.0Omega and 15.0Omega along the rails. The rods are pulled away from the resistor at constant speeds 4.00 m/\s and 2.00 m//s respectively. A uniform magnetic field of magnitude 0.01 T is applied perpendicular to the, plane of the rails. Determine the current in the 5.0Omega resistor.

Two vertical conducting rails separted by distance 1.0m are placed parallel to z -axis as shown in figure. At z=0 , a capacitor of 0.15 F is connected between the rails and a metal rod of mass 100g placed across the rails slides down along the rails. if a constant magnetic fields of 2.0 T exists perpendicular to the plane of the rails, what is the acceleration of the rod?
