Question

Q. d) If now an additional weight is put on the block what change will you observe in

reading of spring balance? Why?
​

Answer 1

Explanation:

Let m be mass ,

m=Dv ; D = density of mass , v = vol.

d = density of water.

m×g=Dv×g=60

fully submerged in water

(D−d)v×g=40

dividing both equations

D

D−d

=

2

solving this :

d
