A conic surface is placed in a uniform electric field E as shown such that field is perpendicular to the surface on the side AB. The base of the cone is of radius R and height of the cone is h 
The angle of cone is θ as shown. Find the magnitude of that flux which enters the cone curved surface from left side. Don’t count the outgoing flux.

B
C
D
none of these
Text Solution
Verified by ExpertsThe correct answer is:
A
Flux entering the cone from side AB will ultimately also pass through area 
and 
So,
