A line charge lambda per unit length is lodgerd uniformly onto the rim of a wheel of mass 'M' radius 'R' . The wheel has non conducting spokes and is free to rotate without friction about axis. A uniform magnetic field extends over an a circular region of radius 'a' within rim. It is given by B= -B 0 k (r what is the angular velocity of the wheel after the field is suddenly switched off?
