Answer:
Explanation:
a )
weight of car = 600 kg .
According to Archimedes principle , for free floatation ,
weight of car = weight of displaced water
600 x 9.8 = v x 10³ x 9.8 , v is volume of water displaced and 10³ kg/ m³ is density of water.
v = .6 m³
required fraction
= .6 / 2
= .3
b )
Let mass of water entering before the start of sinking of car .
mass of maximum displaced volume of water by car = 2 x 10³m³.
(600 + m ) x g = 2 x 10³ x g [ 10³ is density of water ]
600 + m = 2000
m = 1400 kg .
