A sonometer wire fixed at one end has a solid mass M hanging from its other end to produce tension in it. It is found that a 70cm length of wire produces a certain fundamental frequency when plucked. When the same mass M is hanging in water completely submerged in it, it is found that the length of the wire has to be changed by 5cm in order that it will produced the same fundamental frequency. The density of the material of mass M hanging from the wire is `7.26 xx 10^n` . Find n .
