A stone is hung in air from a wire which is stretched over a sonometre. The bridges of the sonometre are L cm apart when the wire is in unison with a tuning fork of frequency N. When the stone is completely immersed in water, the length between the bridges is ℓ cm for re-establishing unison, the specific gravity of the material of the stone is

In order to increase the frequency of transverse oscillations of a stretched wire by 50% its tension must be increased by
