A load of mass M kg is suspended form a steel wire of length 2 m and radius 1.0 mm in Searle’s apparatus experiment. The increase in length produced in the wire is 4.0 mm. now the load is fully immersed in a liquid of relative density 2. The relative density of the material of load is 8. The new value of increase in length of the steel wire is:
(a)
4.0 mm
(b)
3.0 mm
(c)
5.0 mm
(d)
Zero
