Consider a thin cylinder’s shell with radius r and mass m (inertia mr^2). Two sides of the surface have different characteristics. Outer surface of the shell is a conductor with resistivity ρ and thickness δ(δ<<r). And the inner surface is an insulator which is charged uniformly with surface charge density σ. A torque τ works on the cylinder. Find the angular acceleration a of the cylinder when its angular velocity is w! Assume that magnetic field inside the cylinder is uniform and equals to magnetic field at the middle.........[YOU CAN ALSO SEE THE ANSWER IN THE LINK BELOW http://yfrog.com/3t005pg HERE l IS THE LENGTH OF THE CYLINDER
