Question

A rectangular surface of sides 10 cm and 15 cm is placed inside a uniform electric field of 25 V/m, Such that the surface makes an angle of 30° with the direction of electric field. Find the flux of the electric field through the rectangular surface​

Answer 1

Answer:

Answer is ZERO

Bcoz, electric field is in the plane of the surface i.e. x-y plane . And area vector is perpendicular i.e. z-axis . So angle between electric field and area vector is 90 degree.

so flux will be EA Cos 90 which will be equal to Zero
