Two concentric circular coils, C₁ and C₂ are placed in the XY plane. C₁ has 500 turns, and a radius of 1 cm. C₂ has 200 turns and radius of 20 cm. C₂ carries a time dependent current I(t) = (5t² – 2t + 3) A where t is in s. The emf induced in C₁ (in mV), at the instant t = 1 s is \(\frac{4}{X}\). The value of x is _____ .
