For designing a voltmeter of range \( 50 \, \text{V} \) and an ammeter of range \( 10 \, \text{mA} \) using a galvanometer which has a coil of resistance \( 54 \, \Omega \) showing a full scale deflection for \( 1 \, \text{mA} \) as in figure.
(A) for voltmeter \( R \approx 50 \, \text{k}\Omega \) (B) for ammeter \( r \approx 0.2 \, \Omega \)
(C) for ammeter \( r = 6 \, \Omega \) (D) for voltmeter \( R \approx 5 \, \text{k}\Omega \)
(E) for voltmeter \( R \approx 500 \, \Omega \)
