(D) The inductive reactance is given by $X_L = \omega L = 2 \pi f L$.Substituting the given values: $X_L = 2 \times \pi \times 350 \times 0.1 = 70 \pi \approx 70 \times 3.14159 = 219.9 \Omega$.In an $RL$ series circuit,the phase difference $\phi$ between the voltage and the current is given by $\tan \phi = \frac{X_L}{R}$.Substituting the values: $\tan \phi = \frac{219.9}{110} \approx 1.999 \approx 2$.Therefore,the phase difference is $\phi = \tan ^{-1}(2)$.
