Solving Process of the Electrostatic Field Induced by A Point Charge in Angle Space with Electric Image Method

The paper studies and discusses the electric field distribution of internal point charge in angle space formed by conductor,analyses and calculates the image charge distribution and number and how to calculate potential and strength of electric field.Discusses what value from α angle that electric image method can be used or not.When α=π/2、π/3、π,the charge distribution and its electric potential,electric field is calculated respectively.Analyses and discusses the boundedness of electric image method under the condition that α≠π/n(n=1,2,3,…).
