In a certain region of space the electrostatic field depends only on the coordinates x and y as follows. E=0"for"sqrt(x^(2)+y^(2)) lt r_(0) E=a(xhati+yhatj)(x^(2)+y^(2))"for"sqrt(x^(2)+y^(2)) gt r_(0) Where a is a positive constant and hati and hatj are the unit vectors along the X-and Y-axes. find the charge within a sphere of radius 2r_(0) with the centre at the origin. |
