The actual value of resistance R, shown in the figure is 30 Ω. This is measured in an experiment as shown using the standard formula R = V/ I , where V and I are the readings of the voltmeter and ammeter, respectively. If the measured value of R is 5% less, then the internal resistance of the voltmeter is
(1) 570 Ω
(2) 600 Ω
(3) 35 Ω
(4) 350 Ω
