A hollow, insulating spherical shell has a surface charge distribution placed upon it, such that the upper hemisphere has a uniform surface charge density 
, while the lower hemisphere has a uniform surface charge density 
, as shown in the figure. Their interface lies in x-y plane. Which of the following statement (s) is / are correct
- The field at all points of x-y plane within the sphere points in the – ve z-direction
- All points of the x-y plane within the sphere are equipotential
- The field at all points on z-axis outside the sphere point along positive z-direction
- The field at points on z axis which are on either side of origin outside the sphere is in opposite directions.
The correct answer is: The field at all points on z-axis outside the sphere point along positive z-direction
