A galvanometer of resistance \(50~\Omega\) is connected to a battery of \(3\) V along with a resistance of \(2950~\Omega\) in series. A full-scale deflection of \(30\) divisions is obtained in the galvanometer. In order to reduce its deflection to \(20\) divisions, the resistance added in series should be:
1. \(1050~ \Omega\)
2. \(1550~ \Omega\)
3. \(2050~ \Omega\)
4. \(1500~ \Omega\)
1. \(1050~ \Omega\)
2. \(1550~ \Omega\)
3. \(2050~ \Omega\)
4. \(1500~ \Omega\)
