An electric field $E = (2 x \hat{i}) N C^{- 1}$ exists in space. A cube of side $2 m$ is placed in the space as per figure given below. The electric flux through the cube is ______ $Nm^{2} / C$ .

Answer:

16.00

Solution:

$E = 2 x \hat{i} ϕ = E \cdot A$ $ϕ_{in} = - 4 \times 4 = - 16 Nm^{2} / c ϕ_{out} = 8 \times 4 = 32 Nm^{2} / c d_{net} = ϕ_{in +} ϕ_{out} = - 16 + 32 = 16 Nm^{2} / c$
