A cell of emf

3.4\ \text{V}

and internal resistance

3\ \Omega

is connected to an ammeter of resistance

2\ \Omega

and an external resistance of

100\ \Omega

. When a voltmeter is connected across the

100\ \Omega

resistance, the ammeter reading is

0.04\ \text{A}

. Find the voltage reading of the voltmeter and its resistance. Had the voltmeter been ideal, what would its reading have been?
