Physics - Error from Voltmeter?


In the circuit shown above:

* ℰ = 4 V;
* r = 110 Ω;
* R1 = 280 Ω;
* R2 = 370 Ω;
* Internal Resistance of the voltmeter meter = 5 X 103 Ω
* The ammeter is ideal (i.e. its internal resistance is zero.)

a) What is the magnitude of the percentage error the voltmeter introduces when trying measure the potential difference across R1 ? error = ? %
