A teacher in his physics laboratory allotted an experiment to determine the resistance (G) of a galvanometer. Students took the observations for \frac{1}{3} deflection in the galvanometer. Which of the below is true for measuring value of {\G} ? [25-Jun-2022-Shift-1]

Correct Answer is : 13 deflection method can be used and in this case the G equals to twice the value of shunt resistances.

\frac{1}{3} deflection method cannot be used for determining the resistance of the galvanometer.

\frac{1}{3} deflection method can be used and in this case the G equals to twice the value of shunt resistances.

\frac{1}{3} deflection method can be used and in this case, the G equals to three times the value of shunt resistances.

\frac{1}{3} deflection method can be used and in this case the G value equals to the shunt resistances.
