Question

The electric flux through the surface is minimum when the angle between e and a is

Answer 1

Answer:90

Explanation:

Answer 2

The electric flux through the surface is minimum when the angle between E and A is 90°

• Electric flux is the property of an electric field that may be thought of as the number of electric lines of force that intersect a given area. Electric field lines are considered to originate on positive electric charges and terminate on negative charges
• The formula for Electric flux is Ф = EAcos∅
• Area is a positive quantity that can be a minimum of 0. E can be positive or negative, positive if field lines going out of the surface and negative if lines are coming into the surface
• The flux being positive or negative doesn't matter in this question as they asked at which angle, Leaving the condition on ∅. The total flux becomes 0 when ∅ is 90°
• Here ∅ ranging between 0° to 180° and 180° to 360° can be considered to be the same where The sign gets inverted
