AIPMT PRELIMS 2006 Physics Electric Flux MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A square surface of side L m is in the plane of the paper. A uniform electric field also in the plane of the paper, is limited only to the lower half of the square surface, (see figure). The electric flux in SI units associated with the surface is :
A
EL₂/(2ε0)
B
EL₂/2
C
zero
D
EL₂
Correct Answer
Option C
Detailed Explanation
The electric flux is calculated using the formula Φ = E * A, where E is the electric field and A is the area. Since the field is limited to half the surface, the flux is EL₂/(2ε0).
