1. Consider a thin ring of radius R. The ring is uniformly charged with a total charge Q. Write an expression for the linear charge density 1 of the ring. Linear charge density 2. The ring has rotational symmetry. That means the object can be rotated about a fixed axis without changing the overall shape. Which one is this axis? (Call it axis of symmetry). Make a small sketch of the ring and its axis of symmetry. Your goal for the next parts is to calculate the net electric field due to the charged ring at a point P located at a distance z from the center of the ring along the axis of symmetry of the ring. 3. Make a sketch of the ring and the point P. Imagine to divide the ring in many tiny elements of charge dq. Inspecting the symmetry of the problem, what do will be the direction of the net electric field at point P? you think
