assag The length of a potentiometer wire is 600cm and it carries a current of 40mA For a cell of emf 2V and internal resistance 100 the null point is found to be at 500cmn On connecting a voltmeter across the cell the balancing length is decreases by 10cm The voltmeter reading will be a 1 96V b 1 8V c 1 64V d 0 96V The resistance of the voltmeter a 5000 b 290 c 49 d 200
