357269 A wire of length\(10\,\;cm\) and radius\(\sqrt 7 \times {10^{ - 4}}\;m\) is connected across the right gap of a meter bridge. When a resistance of \(4.5\,\,\Omega \) is connected on the left gap by using a resistance box, the balance length is found to be at \(60\;\,cm\) from the left end. If the resistivity of the wire is \(R \times {10^{ - 7}}\,\,\Omega m\), then value of \(R\) is:
