![ELECTRIC FLUX
Write the given and complete solution.
1. A uniform electric field E = 8000 N/C passing through a flat
square area A = 10 m?. Determine the electric flux.
2. A disk of radius 196 mm is oriented with its normal unit
vector fi at 60° to a uniform electric field E of magnitude
5.87 x 103 N/C.
(a) What is the electric flux through the disk?
(b) What is the flux through the disk if n is parallel to E.

3. A hollow sphere has unknown charges distributed
uniformly over its surface. At a distance of 0.63 m from the
center of the sphere, the electric field points radially inward
and has a magnitude of 4.56 x103 N/C. How much charge
is on the sphere?
4. A flat rectangle is placed in a uniform electric field with a
magnitude of 7.8 x 103 N/C. The electric flux through the
rectangle when its face is 45° to the field lines is 89.75
Nm2/C. Find the width of the flat rectangle with a length of
9.45cm.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b82cc96-60c1-4003-bcea-55371104e8e5%2Fb0d997b7-1d60-42ba-98d5-3d2d96edbb8f%2F4kcrtxc_processed.jpeg&w=3840&q=75)
