The question in this practice test says that for an electric field passing through a flat surface perpendicular to it, the electric flux of the electric field through the surface is the product of the electric field’s strength and the area of the surface. A certain flat surface consists of two adjacent squares, where the side length, in meters, of the larger square is 3 times the side length, in meters, of the smaller square. An electric field with strength 29.00 volts per meter passes uniformly through this surface, which is perpendicular to the electric field. If the total electric flux of the electric field through this surface is 4,176 volts⋅meters, what is the electric flux, in volts⋅meters of the electric field through the larger square? I recognized this question from SAT Practice Test #5 in Bluebook. However, there was an error in which this question was written. Instead of 4,176, the question should've said that the "total electric flux of the electric field through this surface is 4,640 volts meters." However, it said 4,176, causing me to calculate differently and set up a ratio of 4176/10=x/9 and having x=3758.4 volts meters. 10 and 9 in this ratio represent the relations of the total area of both squares to the area of the larger square since a side length times 3 is the same as an area times 9. Please fix this error and change 4,176 in the question to 4,640. If the original question were to include 4,176 instead, the answer should be 3,758.4. However, the SAT Practice Test 5 has 4,640.
