A galvanometer of resistance $\displaystyle 50 \Omega$ is connected to a battery of $\displaystyle 3$ V alongwith a resistance of $\displaystyle 2950 \Omega$ in series. A full scale deflection of $\displaystyle 30$ divisions is obtained in the galvanometer. In order to reduce this deflection to $\displaystyle 20$ divisions, the resistance in series should be :
Official answer
(1)
$\displaystyle 4450 \Omega$
