An infinity long uniform line charge distribution of charge per unit length `lambda` lies parallel to the y-axis in the `y-z` plane at `z=sqrt3/2` a(see figure). If the magnitude of the flux of the electric field through the rectangular surface ABCD lying in the `x-y` plane with its centre at the origin is `(lambdaL)/(nepsilon_0)` (`epsilon_0=` permittivity of free space), then the value of n is
