A galvanometer can withstand safely a maximum current of \( 5 \mathrm{~mA} \). It is converted into voltmeter reading upto \( 20 \mathrm{~V} \) by connecting in series an external resistance of \( 3950 \Omega \). The resistance of galvanometer is
(1) \( 48 \Omega \)
(2) \( 44 \Omega \)
(3) \( 36 \Omega \)
(4) \( 50 \Omega \)
