JEE Main 2014 Physics question

A cone of base radius R and height h is located in a uniform electric field parallel to its base. The electric flux entering the cone is:

(1)
(2)EhRCorrect
(3)2EhR
(4)4EhR

Answer: (2)

Solution

The flux entering equals times the area of the cone's projection on a plane perpendicular to . Since the field is parallel to the base, that projection is the axial
