In an L-C-R series circuit, the potential difference
P between the terminals of the inductance is \( 60 \mathrm{~V} \),
W between the terminals of the capacitor is \( 30 \mathrm{~V} \) and that across the resistance is \( 40 \mathrm{~V} \). Then, the supply voltage will be equal to
(1) \( 10 \mathrm{~V} \)
(2) \( 50 \mathrm{~V} \)
(3) \( 70 \mathrm{~V} \)
(4) \( 130 \mathrm{~V} \)
