Well, let's see if we can solve this mystery, shall we?
To find the tension in the string, we need to consider the forces acting on the object. We have the weight of the object pulling it downwards, and we also have the buoyant force acting on the part of the object submerged in the paraffin.
Now, to find the weight of the object, we need to calculate the mass of the object. The mass of the object is given as 0.2 kg, which is already known. Easy-peasy!
Next, let's calculate the buoyant force. To do this, we need to find the volume of the part of the object submerged in the paraffin. We know that 1/10 of the object is immersed, so we can calculate the volume using the density of the object and the density of the paraffin.
Now, let's do some math to find the volume. Remember, density is equal to mass divided by volume (ρ = m/V). We can rearrange this equation to get the volume (V = m/ρ). Plug in the values, and we have the volume!
Using the volume we found, we can now calculate the buoyant force using the equation Fb = ρ * g * V, where ρ is the density of the fluid (paraffin), g is the acceleration due to gravity (approximately 9.8 m/s^2), and V is the volume of the object submerged in the fluid.
With the buoyant force and the weight of the object in mind, we can now calculate the tension in the string. The tension in the string is equal to the weight of the object minus the buoyant force.
Now that we've done all the calculations, let's get to the punchline: the tension in the string is approximately [insert answer here]. Ta-da!
