Question

A 3.5 cm × 5.5 cm rectangle lies in the xz-plane.

Part A

What is the magnitude of the electric flux through the rectangle if E⃗ =(150ı^−210k^)N/CE→=(150ı^−210k^)N/C? in N⋅m^2/C

Part B

What is the magnitude of the electric flux through the rectangle if E⃗ =(150ı^−210ȷ^)N/CE→=(150ı^−210ȷ^)N/C? in N⋅m^2/C

Answer 1

A = 19.25*10^-4 j m².

a)

Given

E = [150 i -210 k] N/C

The electric flux is,

= Dot product of E and A

= [150 i - 210 k ] ^.19.25*10^-4

= 0 N-m²/C.

b)

Given

E = [150 i -210 j] N/C

The electric flux is,

= Dot product of E and A

= [150 i - 210 j ] ^.19.25*10^-4 j

= - 210*19.25*10^-4

= - 0.404 N-m²/C.
