A bollow cylindrical box of length 1m and area of cross section `25 cm^(2)` is placed in a three dimensional co-ordinate system as shown in Fig, The electric field in the
region is given by `vec(E) = 50 x hat(i)` , where E is in `NC^(-1)` and x is in meter. Find
(i) Net flux through the cylinder
(ii) Charge enclosed by the cylinder.
