Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice. The voltmeter has an internal resistance of 8 x 10^9 Ohms and is used to measure the voltage across the resistor R2. Attaching this non-ideal voltmeter decreases the voltage across R2. Calculate the magnitude of this decrease using an emf of 14 V and R1 = R2 = 350 kOhms.
