Flux through a surface

Flux through a surface#

Part 1#

How should a planar surface of area \(A\) be oriented in a uniform electric field of magnitude \(E_0\) such that the electric flux through the surface is a maximum?

Answer Section#

  • Perpendicular to the electric field

  • Parallel to the electric field

  • At a 45 degree angle with respect to the electric field

Part 2#

How should a planar surface of area \(A\) be oriented in a uniform electric field of magnitude \(E_0\) such that the absolute value of electric flux through the surface is a minimum?

Answer Section#

  • Perpendicular to the electric field

  • Parallel to the electric field

  • At a 45 degree angle with respect to the electric field
