Question 771: Electrostatics & Capacitance

Question

A square surface of side L metres is in the plane of the paper. A uniform electric field $$\overrightarrow E $$ (volt/m), also in the plane of the paper is limited only to the lower half of the square surface (see figure). The electric flux in SI inits associated with the surface is

Accepted Answer

Electric flux,  $${\phi _E} = \int {\overrightarrow E .d\overrightarrow S } $$
$$ = \int {EdS\cos 	heta }  = \int {EdS\cos {{90}^o} = 0} $$
The lines are parallel to the surface.
