Angle between direction of electric field and surface

Reference no: EM13650129

A circular surface with a radius of 0.057 m is exposed to a uniformexternal electric field of magnitude 1.44 × 10⁴N/C. The electric flux through the surface is 78 N ·m²/C. What is the angle between the direction of the electric field and the normal to the surface?
