Question

A charge q is placed at the center of an imaginary spherical surface. The electric flux due to this charge through any half of the sphere will be ???

Answer 1

Answer:

Explanation:

for a hemisphere, = total surface area is half of that of the sphere.

the charge Q is inside the sphere. So, by symmetry, the total flux is equally distributed in the two hemispheres. So the flux through one hemisphere will be half of the total flux through the sphere.
