Question

Upthrust on the block if it is held fully immersed in water is $Xkgf$. Find [$\frac{X}{3}$]. {Where , [] is step function}.

• A. $5$
• B. $0$
• C. $4$
• D. $13$

Answer 1

The correct option is A $5$

Upthrust when fully immerge = $Vdg$
$15\times {10}^{-3}\times 1000\times 10=150kg$
$\Rightarrow =15kgf$
$\therefore X/3=5$
