A charge of `1C` 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 `10^(4)pi rad//s.` Find the magnetic field at a point on the axis of rotation at a distance of `0.8m ` from the centre of the path.

A charge of IC 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 10^(4)pi"rad"/s . Find the magnetic field at a point on the axis of rotation at a distance of 0.8 m from the centre of the path

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 10^(4) pi "radian/sec" . Find the magnetic field at a point on the axis ofrotation 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 angnlar frequency. Calculate the magnetic field at a point on the axis at a distance of 0.4m form the centre of the rod.

A uniform metal rod is rotated in horizontal plane about a vertical axis passing through its end at uniform rate. The tension in the rod is

A uniform rod of mass m and length L is free to rotate in the vertical plane about a horizontal axis passing through its end. The rod initially in horizontal position is released. The initial angular acceleration of the rod is:
