Two flat surfaces are exposed to a uniform, horizontal magneticfield of magnitude 0.65 T. The first surface is tilted at an angleof 23° from the horizontal, and a net magnetic flux of 6.0 x10-4 Wb passes through it. The same net magnetic fluxpasses through the second surface. (a) Determinethe area of the first surface. (b) Find the smallest possible value of the area of the second surface.
