Question

the electric flux across a rectangular surface area is placed in uniform electric field making an angle 60 degree with its surface is

Answer 1

Given that,

Angle = 60°

We know that,

Electric flux :

The electric flux is the product of electric field and area of surface.

In mathematically,

$\phi=EA\cos\theta$

We need to calculate the electric flux if the angle is 60°

Using formula of electric flux

$\phi=EA\cos\theta$

Where,

E = electric field

A = area of surface

Put the value of angle

$\phi=EA\cos60$

$\phi=\dfrac{EA}{2}$

Hence, The electric flux is $\dfrac{EA}{2}$

Answer 2

Answer:

Ф= E.Acos∅     ∅ is angle b/w them

        then, Ф = ea.1/2
