Question

a small plane area is rotated in an electric field in which orientation of the area is the flux of electric field through area is maximum?in which orientation is it zero?​

Answer 1

when orientation of area is perpendiculur to the orientation of electric field.....

flux = EAcos90

flux = minimum because cos90=0

when orientation of area is parellar to orientation of electeic field...

flux = EAcos0

flux = maximum because cos0=1
