The electric field intensity at the center of a uniformly charged hemispherical shell is `E_(0)`. Now two portions of the hemisphere are cut from either side, and the remaining portion is shown in fig. If `alpha=beta=pi//3`, then the electric field intensity at the center due to the remaining portion is

A

`(E_(0))/(3)`

B

`(E_(0))/(6)`

C

`(E_(0))/(2)`

D
