Solution

The correct option is A 10
Only the $^{'} i^{'}$ component is E will cause any flux through the y plane. This 'j' component is parallel to the y,z plane so will not push anything through it.
Hence the flux is $\Rightarrow ϕ = 5 (N / C) (2 m^{2}) = 10$

The electric field in a region of space is given by E = 5i +2j N/C. The electric flux due to this field through an area 2m2 lying in the YZ plane, in S.I unit, is

The correct option is A 10Only the ′i′ component is E will cause any flux through the y plane. This 'j' component is parallel to the y,z plane so will not push anything through it.Hence the flux is⇒ϕ=5(N/C)(2m2)=10
