A long thin wooden cylindrical pipe of radius R carrying a uniform surface charge density is rotating about its axis with an angular velocity that increases slowly with time t as kt where k is a positive constant Which of the following statements is are correct for the region inside the pipe Jor The magnetic field is not constant with time B The magnetic field is constant but not uniform and the electric field is uniform but not constant T DI total energy density due to both the fields varies with time Both the magnetic and the electric fields are uniform and constant
