Problem statement

The electric field at point P(0,y) inside a positively charged hemispherical shell of radius R, is given to be E. What is the field at the point Q(0, -y)? What is the direction of the y-component of the electric field at any general point G inside the hemisphere? What is the direction of the horizontal component of the electric field at any point B on the base surface?
