Weight of the Body and Buoyant Force:
When a body is immersed in a fluid, it experiences two opposing forces: its weight and the buoyant force. The weight of the body is determined by its mass and the acceleration due to gravity. In this case, the mass of the body is 11 kg.

Archimedes' Principle:
According to Archimedes' principle, the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. This principle helps us determine whether the body will float or sink.

Weight of the Water Displaced:
The weight of the water displaced by the body is given as 10 kg. This means that the buoyant force acting on the body will be equal to 10 kg.

Comparison of Weight and Buoyant Force:
To determine whether the body will float or sink, we need to compare the weight of the body and the buoyant force acting on it.

- If the weight of the body is less than the buoyant force, the body will float.
- If the weight of the body is greater than the buoyant force, the body will sink.
- If the weight of the body is equal to the buoyant force, the body will remain in equilibrium at any level of immersion.

Calculating the Weight of the Body:
The weight of the body can be calculated using the formula: weight = mass * acceleration due to gravity. Assuming the acceleration due to gravity is 9.8 m/s^2, the weight of the body is:

Weight = 11 kg * 9.8 m/s^2 = 107.8 N

Comparing the Weight and Buoyant Force:
Since the weight of the body is greater than the buoyant force (107.8 N > 10 kg), the body will sink when immersed in the water tank.

Conclusion:
In conclusion, when a body is immersed in a water tank, the weight of the water displaced by the body is 10 kg, while the weight of the body itself is 107.8 N. Since the weight of the body is greater than the buoyant force acting on it, the body will sink in the water tank.

Sink because it displaces water 10 kg and the total maSs of body is 11kg ...
then it displaces water 10 kg...then how is it possible..
