A spring balance reads 10 kg when a bucket of water is suspended from it. What is the reading on spring balance when 2.2 kg icecube is put into it? (Density of ice is 0.920gm/cc).
When an ice cube is put into the bucket, then the total mass of the system suspended from the spring is given by 10 + 2.2 kg = 12.2 kg.
That is, the spring balance will read 12.2 kg.
