Question

Coordinates of a square are given as (-1, 1,0)m, (1, 1,0)m, (-1,-1,0)m, (1, -1,0)m. If electric field is 10 V/m along z-axis, electric flux through square face is

Answer 1

Answer:

answer is 40 vm explained above

Answer 2

The electric flux through square face is 40 V-m.

Explanation:

Given that,

Coordinates of a square are given as,

(-1,1,0), (1,1,0), (-1,-1,0), (1,-1,0)

Electric field = 10 V/m

Side of the square is 2 m

We need to calculate the electric flux

Using formula of electric flux

$\phi=EA\cos\theta$

Where, E = electric field

A = area

Put the value into the formula

$\phi=10\times4\sin90$

$\phi=40\ V-m$

Hence, The electric flux through square face is 40 V-m.
