vecE=2000 hatk, vecA=10 × 20 × 10-4 hatk φ= vecE ⋅ vecA=40 Vm

Q. In a certain region of space, there exists a uniform electric field of value $2 \times 1 0^{2} \hat{k} V m^{- 1}$ . A rectangular coil of dimension $10 c m \times 20 c m$ is placed in the $x y$ plane. The electric flux through the coil is

zero

$30 Vm$

$40 Vm$

$50 Vm$

$E = 2000 \hat{k}, A = 10 \times 20 \times 1 0^{- 4} \hat{k}$
$ϕ = E \cdot A = 40 Vm$

Q. In a certain region of space, there exists a uniform electric field of value 2×102k^Vm−1. A rectangular coil of dimension 10cm×20cm is placed in the xy plane. The electric flux through the coil is

zero

30Vm

40Vm

50Vm

E=2000k^,A=10×20×10−4k^ ϕ=E⋅A=40Vm
