Question

PHYS PHYSICS - VII PART- NEWTON'S LAWS OF MOTION 7. A boy is carrying a bucket of water in one hand and a piece of plastic in the other. After transferring the [ ] plastic piece to the bucket (in which it floats) the boy will carry a) same load as before b) more load as before c) less load as before d) either less or more load, depending on the density of plastic nocition then​

Answer 1

Answer:

The boy will carry same load as before.  

When boy transfer plaster to water, even though plaster floats, it  apply weight on water which will be managed by buoyant force. Consider this force as action, now water is acted upon by reaction.  

So, overall force on bucket is weight of water+ reaction

this equals initial weight on boy.
