Shows rod PQ of mass m and resistance r moving on two fixed, resistanceless, smooth conducting rails (closed on both sides by resistances R_(1) and R_(2) ). Find the current in the rod (at the instant its velocity is v ).

Shows rod PQ of mass m and resistance r moving on two fixed, resistanceless, smooth conducting rails (closed on both sides by resistances R_(1) and R_(2) ). Find the current in the rod (at the instant its velocity is v ).

In the figure shown PQRS is a fixed resistanceless conducting frame in a uniform and constant magnetic field of strength B . A rod EF of mass m length l and resistance R can smoothly move on this frame.A capacitor charged to a potential difference V_(0) initially is connected as shown in the figure.Find the velocity of the rod as function of time t if it is released at t=0 from rest.

A uniform rod AB of mass m and length l is placed over two smooth conducting rails P and Q. If the witch shown as closed at t=0, find the velocity of rod AB as a function of time.

A rod of mass m and resistance R slides on frictionless and resistance less rails at distance l apart, that include a source of emf E_0 (see figure). The rod is initially at rest. Find the expression for the a. Velocity of the rod v(t). b. current in the loop i(t).

A conducting rod PQ of mass m and length l is placed on two long parallel (smooth and conducting) rails connected to a capacitor as shown. The rod PQ is connected to a non conducting spring of spring constant k , which is initially in relaxed state. The entire arrangement is placed in a magnetic feild perpendicular to the plane of figure. Neglect the resistance of the rails and rod. Now, the rod is imparted a velocity v_(0) towards right, then acceleration of the rod as a function of its displacement x given by
