Question 17: NCERT Solutions for 12th Class Physics: Chapter 6-Electromagnetic Induction
A line charge λ per unit length is lodged uniformly onto the rim of a wheel of mass M and radius R. The wheel has light non-conducting spokes and is free to rotate without friction about its axis. A uniform magnetic field extends over a circular region within the rim.
It is given by = o (otherwise) What is the angular velocity of the wheel after the field is suddenly switched off?
