In the circuit shown in the figure, reading of voltmeter is V1 when only S1 is closed, V2 when only S2 is closed and V3 when both S1 and S2 are closed. Choose the correct relation between V1, V2 and V3.
When only S1 is closed,
Reading of the voltmeter V1=E4R×3R=3E4
When only S2 is closed,
Reading of the voltmeter V2=E7R×6R=6E7
When both S1 and S2 are closed,
Reading of the voltmeter V3=E3R×2R=2E3
