A solid iron ball of mass 500 g is dropped in mercury contained in a beaker.
What will be the apparent weight of the ball?

Explanation

To find the apparent weight of a solid iron ball of mass 500 g when it is dropped into mercury, we can follow these steps:

### Step 1: Understand the concept of apparent weight
The apparent weight of an object submerged in a fluid is the weight of the object minus the buoyant force (upthrust) acting on it. The buoyant force is equal to the weight of the fluid displaced by the object.

### Step 2: Calculate the weight of the iron ball
The weight of the iron ball can be calculated using the formula:
\[ \text{Weight} = \text{mass} \times g \]
