Question

A wire loaded by weight of density 7800 kg/m³ is stretched to length of 1m. On immersing the weight in liquid of density 1300kg/m³, the length shortens by 6mm. Find the original length of the wire.

Solution

Given,
Density of the load, ρ = 7800 kg/m³
Length of the wire, l = 1 m
Density of liquid, = 1300 kg/m³
Let, V be the volume of weight suspended from the wire.

Therefore, tension in the wire when load is in the air is equal to,
