from the diagram above, the inductive reactance and the resistance R are respectively

50Ω and 45Ω

25Ω and 51Ω

20Ω and 50Ω

10Ω and 50Ω

Explanation

The inductive reactance is given as
Xl = 2πfl
= 2 x ⁵⁰/_π x 0.1
= 10Ω
Again from ohms law,
R = ^V/_I = ⁷⁵/_1.5 = 50Ω
∴ Thus the inductive reactance and the resistance are respectively 10Ω, and 50Ω
