A flat sheet is in the shape of a rectangle with sides of lengths 0.400 m and 0.600 m. The sheet is immersed in a uniform electric field of magnitude 71.7 N/C that is directed at 20 ∘ from the plane of the

Step-by-step explanation:

We are given that

Length of rectangle sheet=l=0.4 m

Breadth of rectangle sheet=b=0.6 m

Electric field=E=71.7 N/C

Angle

The angle between electric field vector and area vector=

We have to find the magnitude of electric flux passing through the sheet.

Area of rectangle sheet=

Magnitude of electric flux passing through the sheet=

Magnitude of electric flux passing through the sheet=

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
