Two concentric rings of radii r and 2r are placed with centre at origin Two charges q each are fixed at the diametrically opposite points of the rings as shown in figure Smaller ring is now rotated by an angle 90 about Z axis then it is again rotated by 90 about Y axis Find the work done by electrostatic forces in each step If finally larger ring is rotated by 90 about X axis find the total work required to perform all three steps 9 9 9
