A uniform electric field is given as `[E = 100 hat(i) N//C]` for `x gt 0 and E- 100 hat(i) N//C` for `x lt 0`. A right circular cylinder of length 20 cm and radius 5cm has its centre at the origin and its axis along the X-axis, so that one face is at `x= +10` cm and other is at `x= -10`cm.
What is the flux through the side of cylinder?

Verified by Experts

For any point on the side of the cylinder, `E bot Delta S` and hence `E. Delta S=0 [ because cos 90^(@)=0]`
`therefore` Flux out of the side of the cylinder= 0.
