A cоnducting sphere (shоwn in grey in the drаwing) оf rаdius R hаs a number q of excess electrons distributed uniformly over its surface. A spherically-shaped Gaussian surface with a radius r < R is represented in the drawing by the dashed circle (inside the conducting sphere). What is the magnitude of the electric field at the distance r?
