The total length of a sonometer wire fixed between two bridges is 110cm110\mathrm{cm}110cm. Now, two more bridges are placed to divide the length of the wire in the ratio 6:3:26:3:26:3:2. If the tension in the wire is 400N400N400N and the mass per unit length of the wire is 0.01kgm−10.01\mathrm{kg}{m}^{-1}0.01kgm−1, then the minimum common frequency with which all the three parts can vibrate, is
