Question

The density of iron is 7800 kg/ m3 and density of mercury is 13600 kg/m3.state wether iron sinks or floats in mercury.​

Answer 1

Answer:

Yes Iron floats on Mercury

Explanation:

as Iron is less dence than Mercury the buyont force applied on Iron is larger than its wheight

Answer 2

Answer:

ρiron=7.8×103kg/m3

ρHg=13.6×103kg./m3

Let volume of body=V

Weight of body = buoyant force

ρironVg=ρHgV′g

7.8×103×V=13.6×103×V′

V′=13.6×1037.8×103

V′=13678V

V′=0.57V

Volume outside =V−V′

V−0.57V

=0.43V
