Question
The square surface shown has a side length of 2.5 mm. It is in a uniform electric field with a magnitude of 2000 N/C, which makes an angle of 36.0 degrees with a normal to the square surface as shown. Take that normal to define outward direction for the surface. Calculate the electric flux through the surface.
The square surface shown has a side length of 2.5 mm. It is in a uniform electric field with a magnitude of 2000 N/C, which makes an angle of 36.0 degrees with a normal to the square surface as shown. Take that normal to define outward direction for the surface. Calculate the electric flux through the surface.Explanation / Answer
flux = E . A cos 36 ;
flux = 2000 * ( 2.5 e -3 )^2 cos 36 = 1.0112 e -2 <---ans
