A hollow insulating spherical shell has a surfac charge distribution placed upon it, such that the upper hemisphere has a uniform surface charge density sigma. While the lower hemisphere has a uniform surface charge density -sigma.as shown in the figure. Their interface lies in x-y plane which

Answer»

The field at all POINTS of x-yplane within the SPHERE points in the - ve z-directior.
All the 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 sphre is in opposite DIRECTIONS.
