Answer:
The density of the other liquid = 700 kg/m³
Explanation:
Given that
balance in the air = 29 N
Lets take the mass of the object = m
Volume of the object = V
m g = 29 N -----------1 ( assuming that bouncy force due to air is zero)
Spring balance in the water :
Bouncy force due to water = ρ V g
Density of water = 1000 kg/m³
Spring balance = 19 N
19 + ρ V g = m g
19 + ρ V g = 29
ρ V g =10 ----------2
Spring balance in the another liquid :
Bouncy force due to water = d V g
d=Density of the other liquid
Spring balance = 22 N
22 + d V g = m g
22 + d V g = 29
d V g =7 ----------3
Form equation 2 and 3
d= 700 kg/m³
Therefore the density of the other liquid = 700 kg/m³
