1. The problem statement, all variables and given/known data A cone of height H and base radius A is charged with charge Q uniformly distributed in all its volume. Find electrostatic field intensity at the top of the cone. DATA: H, A, Q 2. Relevant equations E=ρ/(4πε0) ∫Ω dΩ/R2) and R is a vector (rr^+zz^) r^ and z^ are versors 3. The attempt at a solution Don't have idea how to integrate this, hope anyone can help me.
