Question

Densities of few objects are given below:
$\begin{array}{cc}\text{Object}& \text{Density(g/L)}\\ \text{i. Copper}& \text{a. 8.96}\\ \text{ii. Mild steel}& \text{b. 7.85}\\ \text{iii. Water}& \text{c. 1.00}\end{array}$
What would be the observation if copper and mild steel are placed in water?

• A. Copper floats and mild steel sinks
• B. Copper sinks and mild steel floats
• C. Copper and mild steel both sink
• D. Copper and mild steel both floats

Answer 1

The correct option is C Copper and mild steel both sink

Objects having more density than water sinks in it. Objects having less density than water floats on it.
Copper and mild steel have densities much more than that of water so both will sink in it.
