357260 \(50\, \Omega\) and \(100\, \Omega\) resistors are connected in series. This connection is connected with a battery of \(2.4\;V\). When a voltmeter of \(100\, \Omega\) resistance is connected across \(100\, \Omega\) resistor, then the reading of the voltmeter will be

1 \(1.6\;V\)
2 \(1.0\;V\)
3 \(1.2\;V\)
4 \(2.0\;V\)
