A point charge q is placed at the origin. Calculate the electric flux through the open hemispherical surface `(x-a)^2+y^2+z^2=a^2,xgea`

Answer

A, B

Explanation

a.
Flux passing through hemisphere = flux passing through circular surface of the hemisphere. For finding flux through circular surface of hemisphere we can again use the concept used i above problem.

`phi=(q(1-costheta))/(2epsilon_0)`
`=1/(2epsilon_0)(1-cos45^@)`
`=q/(2epsilon_0)(1-1/sqrt2)`
