Since the surface of the conductor is equipotential, the lines of the electric field of the charged conducting ball leave the surface of the ball perpendicular to it. If the charge on the surface of the ball is q, then the electric field outside the ball is the same as the field of a point charge q located in the center of the conducting ball.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
