A body weight 4.8g in air, 2.8g in water and 3.2g in kerosine calculate the ratio of the fluid on which it float

To calculate the ratio of the fluid on which the body floats, we need to determine the buoyant force acting on the body in each fluid.

Buoyant force is the force exerted on an object immersed in a fluid and is equal to the weight of the fluid displaced by the object.

First, let's calculate the buoyant force in water:

- Weight in air = 4.8g
- Weight in water = 2.8g

Buoyant force in water = Weight in air - Weight in water
Buoyant force in water = 4.8g - 2.8g
Buoyant force in water = 2g

Next, let's calculate the buoyant force in kerosene:

- Weight in air = 4.8g
- Weight in kerosene = 3.2g

Buoyant force in kerosene = Weight in air - Weight in kerosene
Buoyant force in kerosene = 4.8g - 3.2g
Buoyant force in kerosene = 1.6g

Now, to find the ratio, we divide the buoyant force in water by the buoyant force in kerosene:

Ratio = Buoyant force in water / Buoyant force in kerosene
Ratio = 2g / 1.6g
Ratio = 1.25

Therefore, the ratio of the fluid on which the body floats is 1.25.
