Question

A plane surface is rotated in a uniform electric field. When is the flux of the electric field through the surface maximum? 

a. When the surface is perpendicular to the field 

b. When the surface is parallel to the field 

c. When the surface is at an angle of 30^o with the field 

d. When the surface is at an angle of 45^o with the field

Answer 1

When a surface is parallel to equipotential surface around a charge, the flux through the surface is maximum
