Question
I am not a Gold memeber so I can't see this answer and I needit badly! Can someone please post it. Thanks! *A unifrom electric field of magnitude 25,000 N/C makes anangle of 37 degrees with a plane surface area 0.0153 m squared.What is the electric flux through the surface?

Explanation / Answer
Apply gauss's law Flux = E * projected area Flux = E * sin * A (Be sure to look at the drawing with the question -- is it 37degrees with respect to the plane surface or 37 degrees withrespect to the perpendicular to the plane surface. If it isthe latter, the formula is Flux = E * cos * A) Flux = 248 N-m2/C Ref:
