Answer:
(2). The mass of the body is 62.5 kg.
Explanation:
Given that,
Mass m = 500 kg
Distance h= 8 cm
Weight of the body = buoyant force
Here, m = mass
= density
h = height,
....(I)
If a body of mass m is placed on the raft, then submerged part changes to 9 cm.
Therefore,
....(II)
on dividing equation (I) by equation (II)
Hence, The mass of the body is 62.5 kg.
