A charge q is placed at the centre of the open end of a cylindrical vessel. The flux of electric field through the surface of vessel is
A
zero
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
To apply Gauss' theorem it is essential that charge should be placed inside a closed surface. So imagine on another similar cylindrical vessel above it. So, the flux through the surface will be half of the total flux.
