Question

a charge q is placed just above the centre of horizontal circle of radius r and a hemisphere about this is erected about the charge. compute the flux through the closed surface that consists of the hemisphere and the planar circle. do not use gauss law​

Answer 1

Answer:

q / 2e0

Explanation:

The flux of electric field due to a charge placed at the center of sphere

                                      =  q /  e0

and we know hemisphere is half of sphere so we divide it by 1/2

​  

∴ the flux of electric field due to a charge placed at the center of hemisphere                                                                    

thus we have answer i.e       = q/2e0
