4 9 A charge of 1 coul is placed at one end of a non conducting rod of length 0 6m the rod is rotated in a vertical plane about a horizontal axis passing through the other end of the rod with angular frequency 104 T radian sec Find the magnetic field at a point on the axis of rotation at a distance of 0 8 from the centre of the path Now half of the charge is removed from one end and placed on the other end The rod is rotated in a vertical plane about horizontal axis passing through the mid point of the rod with the same angular frequency Calculate the magnetic field at a point on the axis at a distance of 0 4m form the centre of the rod
