A) 0. 15 volt
B) 0.15 volt
C) 0.5 volt
D) ? 0.05 volt
Correct Answer: D
Solution :
In a voltmeter \[V\propto l\] \[V=kl\] Now, it is given E = 1.1 volt for \[{{l}_{1}}=440cm\] and V = 0.5 volt for \[{{l}_{2}}=220cm\] Let the error in reading of voltmeter be \[\Delta V\] then, = 400 K and \[(0.5\Delta V)=220K.\] \[\Rightarrow \]\[\frac{1.1}{440}=\frac{0.5-\Delta V}{220}\] \[\therefore \]\[\Delta V=-0.05\]voltYou need to login to perform this action.
