A load of mass M kg is suspended from a steel wire of length 2m and radius 1.0mm in Searle's apparatus experiment. The increase in length produced in the wire is 4.0mm. 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 the increase in the length of the steel wire is:
A) 4.00 mm
B) 3.00 mm
C) 6.00 mm
D) zero
