Two spheres A and B, each of volume `100 "cm"^3` are placed on water (density = `1.0 "g cm"^(-3)`). The sphere A is made of wood of density `0.3 "g cm"^(-3)` and the sphere B is made of iron of density `8.9 "g cm"^(-3)` .
Find the weight of each sphere

Explanation

To find the weight of each sphere A and B, we will use the formula for weight, which is given by:

\[ \text{Weight} = \text{Mass} \times g \]

where \( g \) is the acceleration due to gravity. However, in this case, we will express weight in grams-force (GF), which is equivalent to the mass in grams since we are using the metric system where \( g \approx 1 \, \text{g/cm}^3 \).
