A ring with a uniform charge `Q` and radius `R`, is placed in the `yz` plane with its centre at the origin

Options

A. The field at the origin is zero
B. The field at the origin is `(1)/(4 pi epsi_(0)) (Q)/(R)`
C. The field at the point `(x, 0, 0)` is `(1)/(4 pi epsi_(0)) (Q)/(R)`
D. The field at the point `(x, 0, 0)` is `(1)/(4 pi epsi_(0)) (Q)/(R^(2) + x^(2))`
