A point charge is placed at the origin. Calculate the electric flux through the open hemispherical surface :(x-a)2 +y2 + z2 = a2
x> or = a.
The Attempt at a Solution
There is no diagram but this is how i visualised the question(please refer to attachment)....
Now i was thinking of proceeing via solid angle method but it wont work here i guess because each point on the spere is not equidistant from the charge so the field isnt uniform......So how to go about it?
