Apparent weight of immersed bodies

In summary, the apparent weight of an immersed body is the weight that it appears to have when submerged in a fluid, taking into account the buoyant force. It can be calculated using the formula: Apparent weight = Actual weight - Buoyant force. The factors that affect it include the density of the fluid, the volume of the body, and the acceleration due to gravity, as well as the shape and orientation of the body. The apparent weight is directly proportional to the density of the body. It differs from the true weight, which is the weight of the object in a vacuum without any external forces.

Homework Statement


An object has a weight of 250N, when weighed by spring balance. The same object is fully immersed in water, then the spring balance reading shows, 150N. How to determine the relative density of the object.

What weight of water does its volume displace?
 

1. What is the apparent weight of an immersed body?

The apparent weight of an immersed body is the weight that the body appears to have when submerged in a fluid. It is affected by the buoyant force of the fluid, which counteracts the weight of the body.

2. How is the apparent weight of an immersed body calculated?

The apparent weight of an immersed body can be calculated using the formula: Apparent weight = Actual weight - Buoyant force. The buoyant force is equal to the weight of the fluid displaced by the body.

3. What factors affect the apparent weight of an immersed body?

The apparent weight of an immersed body is affected by the density of the fluid, the volume of the body, and the acceleration due to gravity. It is also affected by the shape and orientation of the body in the fluid.

4. How does the apparent weight of an immersed body relate to its density?

The apparent weight of an immersed body is directly proportional to its density. This means that as the density of the body increases, its apparent weight will also increase. This is due to the fact that a denser body will displace more fluid and therefore experience a greater buoyant force.

5. What is the difference between apparent weight and true weight?

The true weight of an object is its weight in a vacuum, without any external forces acting on it. The apparent weight, on the other hand, is the weight the object appears to have when submerged in a fluid. It is affected by the buoyant force of the fluid and may be different from the true weight.
