357278 Two unknown resistances are connected in two gaps of a meter - bridge. The null point is obtained at 40 \(cm\) from left end. A \(30\Omega \) resistance is connected in series with the smaller of the two resistances, the null point shifts by 20 \(cm\) to the right end. The value of smaller resistance in \(\Omega \) is

In an experiment to determine the temperature coefficient of resistance of a conductor, a coil of wire \({X}\) is immersed in a liquid. It is heated by an external agent. A meter bridge set up is used to determine resistance of the coil \({X}\) at different temperatures. The balancing points measured at temperatures \({t_{1}=0^{\circ} {C}}\) and \({t_{2}=100^{\circ} {C}}\) are \(50\,cm\) and \(60\,cm\) respectively. If the standard resistance taken out is \(S = 4\,\Omega \) in both trials, the temperature coefficient of the coil is
