Question

A body of volume $100cc$ is immersed completely in water contained in a jar. The weight of water and the jar before immersion of the body was $700gwt$. After immersion weight of water and jar will be

• A. $700gwt.$
• B. $800gwt.$
• C. $500gwt.$
• D. $100gwt.$

Answer 1

The correct option is B. $800gwt.$

For a body to be completely immersed its density should be more than that of water hence

$\rho \ge 1g/cc$

Therefore,

$mass\ge 100gm$

Hence net mass $700+m\ge 800gwt$.
