A box \( \mathrm{P} \) and a coil \( \mathrm{Q} \) are connected in series with an ac source of variable frequency. The emf of source at \( 10 \mathrm{~V} \). Box \( \mathrm{P} \) contains a capacitance of \( 1 \mu \mathrm{F} \) in
P
series with a resistance of \( 32 \Omega \) coil. \( Q \) has a selfinductance \( 4.9 \mathrm{mH} \) and a resistance of \( 68 \Omega \) series. The frequency is adjusted so that the maximum current flows in \( \mathrm{P} \) and \( \mathrm{Q} \). The voltage across \( \mathrm{P} \) will be (Approximately)
(1) \( 2.2 \mathrm{~V} \)
(2) \( 5.3 \mathrm{~V} \)
(3) \( 7.7 \mathrm{~V} \)
(4) \( 9.2 \mathrm{~V} \)
