Circuit consists of a series combination of 6.00 kΩ and 4.50 kΩ resistors connected

Circuit consists of a series combination of 6.00 kΩ and 4.50 kΩ resistors connected across a 50.0 V battery having negligible internal resistance. You want to measure the true potential difference (that is, the potential difference without the meter present) across the 4.50 resistor using a voltmeter having an internal resistance of 10.0 kΩ. (a) What potential difference does the voltmeter measure across the 5.00−kΩ resistor? (b) What is the true potential difference across this resistor when the meter is not present?
