Given: A charge Q is placed just above the center of a horizontal circle of radius R and a hemisphere
To find: The flux through the closed surface that consists of the hemisphere and the planar circle.
Solution:
- We have given that A charge Q is placed just above the center of a horizontal circle of radius R and a hemisphere.
- So now, the flux of electric field due to a charge which is placed at the center of sphere will be : q / ∈o
- But hemisphere is half of sphere.
- So, we will multiply it by 1/2, we get:
= q / ∈o x 1 / 2
= q / 2∈o
Answer:
So, the flux of electric field due to a charge placed at the center of hemisphere is q / 2∈o
