# A solid insulating cone has a uniform charge density of p and a total charge of Q. The base of the cone has a radius of R and a height of h. We wish to find the electric field on a point charge of q' at point A, located at the tip of the cone.A. Draw a sketch showing the coordinate system you will use and the direction of the electric field.B. Clearly indicate the charge element, dq, you will use for the integration in your sketch.C. Set up the integration. That is express the electric field, E, as a constant times an integral over a single variable.D. Perform the integration to find E in terms of Q,R and h.
