Question

A light circular cone buoy is pressed by a $500N$ force as shown in figure then the path depth upto which it will submerge is

• A. $1.7m$
• B. $2.0m$
• C. $2.1m$
• D. $3.0m$

Answer 1

The correct option is A $1.7m$

A light circular conebuoyis pressed by $500N$

$F=500N$

$500=h\times \rho g=h\times 1000\times 10$

$h=\frac{500}{1000\times 10}=\frac{1}{20}=0.053-0.05=2.95-0.30=1.65\approx 1.7m$
