A bucket of water is hanging from a spring balance. An iron piece is suspended into water without touching sides of bucket from another support. The spring balance reading will
A. Increase
B. Decrease
C. Remain same
D. Increase/decrease depending on depth of immersion
Answer: Option C
Solution (By Examveda Team)
When an iron piece is suspended into the water without touching the sides of the bucket, the volume of water displaced by the iron piece is equal to the volume of the iron piece submerged. According to Archimedes' principle, the buoyant force acting on the iron piece (equal to the weight of the water displaced) is equal to the weight of the iron piece itself. Therefore, the net effect on the spring balance due to the addition of the iron piece is zero, and the reading of the spring balance will remain the same.This Question Belongs to Mechanical Engineering >> Hydraulics And Fluid Mechanics In ME
Due to buoyancy force acting on the iron piece the spring balance reading will increase.

When the piece of iron is lowered into the water, the water level in the bucket increases. And so the pressure at the bottom of bucket also increases. Thus the total thrust at the botto also increases. Therefore the spring balance reading increases.
