A 10g mass suspended from a string is immersed into a liquid

Click For Summary
SUMMARY

The discussion focuses on the behavior of a 10g mass suspended in a liquid and its impact on the reading of a weighing scale. Initially, when the mass is held above the bottom of the beaker, the scale reads 500g plus the upthrust (X Newton). When the mass is allowed to rest on the bottom of the beaker, the reading on the scale remains unchanged at 500g, as the weight of the mass is transferred to the liquid, resulting in an equal and opposite reaction that does not affect the total weight measured by the scale.

PREREQUISITES
  • Understanding of buoyancy and upthrust forces
  • Basic principles of weight measurement
  • Knowledge of Newton's Third Law of Motion
  • Familiarity with the concept of equilibrium in fluid mechanics
NEXT STEPS
  • Explore the principles of buoyancy in Archimedes' principle
  • Study the effects of submerged objects on fluid displacement
  • Learn about Newton's laws and their applications in fluid dynamics
  • Investigate the design and calibration of weighing scales in different environments
USEFUL FOR

Students studying physics, educators teaching fluid mechanics, and anyone interested in understanding the principles of buoyancy and weight measurement in liquids.

A 10g mass is suspended from a string and immersed in a beaker of liquid(Weight of beaker and liquid = 500g). A boy hold the string with his hand not letting the 10g mass touch the bottom of the beaker. (let upthrust generated by mass be X Newton.)

Qn: what would be the reading on the weighing scale?

The boy repeat the process again and this time round, he let the 10g mass sits on the bottom of the beaker.

Qn: Would there be any change of reading in the weighing scale?
