In a certain region of space the electrostatic field depends only on the coordinates x and y as follows E 0 for x y ro 2 E a xi y x y for x y ro where a is a positive constant and i and are the unit vec tors along the X and Y axes Find the charge within a sphere of radius 2r with the centre at the origin
