In a meter Bridge experiment resistance$x$is connected in the right gap. When$R_1$and$R_2$are connected in the left gap separately the balance points are$40\mathrm{ }\mathrm{c}\mathrm{m}$and$50\mathrm{ }\mathrm{c}\mathrm{m}$respectively from the left end. Now if both$R_1\mathrm{ }\&\mathrm{ }{R}_2$are connected in series in the left gap with$x$in the right gap then what will be the new balance point from the left end (in$\mathrm{cm}$)?
