1. The upthrust of the solid is equal to the weight of the water displaced by the solid. This is given by Archimedes' principle, which states that the upthrust is equal to the weight of the fluid displaced by the object.
The weight of the solid is given by mass x gravitational acceleration, which is approximately 9.8 m/s^2. Thus, the weight of the solid is 1.7 kg x 9.8 m/s^2 = 16.66 N.
Since the tension in the string is 6 N, the upthrust must also be 6 N to achieve equilibrium. Therefore, the upthrust of the solid is 6 N.
2. The volume of the solid can be calculated using the equation for upthrust:
Upthrust = weight of water displaced by the solid
The density of water is 1000 kg/m^3.
density of water x volume of solid x gravitational acceleration = weight of water displaced by the solid
1000 kg/m^3 x volume of solid x 9.8 m/s^2 = 6 N
Volume of solid = 6 N / (1000 kg/m^3 x 9.8 m/s^2) = 0.0006122 m^3
3. The density of the solid can be calculated using the equation for density:
Density = mass / volume
Density = 1.7 kg / 0.0006122 m^3 = 2781 kg/m^3
4. The relative density of the solid can be calculated by comparing the density of the solid to the density of water:
Relative Density = Density of solid / Density of water
Relative Density = 2781 kg/m^3 / 1000 kg/m^3 = 2.781
A solid of mass 1.7kg suspended by a string is completely in water if the tension in the spring is 6N calculate
