a) A surface completely surrounds a 7.8 × 10^-6 C charge. Find the electric flux through this surface when the surface is (a) a sphere with a radius of 0.74 m, (b) a sphere with a radius of 0.32 m, and (c) a cube with edges that are 0.29 m long.

b) A circular surface with a radius of 0.057 m is exposed to a uniform electric field of magnitude 1.84 × 10⁴ N/C. The electric flux through the surface is 75 N·m²/C. What is the angle between the direction of the electric field and the normal to the surface?
