QAIPMT-2010-Ph-2069: NEET 2010 Physics - Class 12 AIPMT-2010-Ph-2069 Solution: A square surface of side L meter in the plane of the paper is…

A square surface of side L meter in the plane of the paper is placed in a uniform electric field E(volt/m) acting along the same plane at an angle θ\theta with the horizontal side of the square as shown in figure. The electric flux linked to the surface, in units of volt.m is

Multiple Choice Options

  • A EL2EL^2
  • B EL2cos⁡θEL^2\cos\theta
  • C EL2sin⁡θEL^2\sin\theta
  • D zero

Step-by-Step Verified Solution

Electric flux, _ = EA cos _ , where _ = angle between E and normal to the surface. Here, _ = � 2 _ _ = 0
