A Solid weighs 50 gf in air and 44 gf when completely immersed in water. Calculate:
(i) the upthrust,
(ii) the volume of the solid, and
(iii) the relative density of the solid.

Explanation

To solve the problem step by step, we will calculate the upthrust, the volume of the solid, and the relative density of the solid based on the information provided.

### Step 1: Calculate the Upthrust
The upthrust (or buoyant force) can be calculated using the formula:
\[ \text{Upthrust} = W_1 - W_2 \]
where:
