A cubical block is floating in a liquid with half of its volume immersed in the liquid. When the whole system accelerates upwards with a net acceleration of $g/3$. The fraction of volume immersed in the liquid will be :-
$\frac{1}{2}$
$\frac{3}{8}$
$\frac{2}{3}$
$\frac{3}{4}$
A block of steel of size $5 \times 5 \times 5 \,cm ^3$ is weighed in water. If relative density of steel is $7$ , its apparent weight is ........... $g wt$

If the terminal speed of a sphere of gold (density $= 19.5\, kg/m^3$) is $0.2\, m/s$ in a viscous liquid (density $= 1.5\, kg/m^3$), find the terminal speed of a sphere of silver (density $= 10.5\, kg/m^3$) of the same size in the same liquid....... $m/s$
The graph between terminal velocity (along $y-$ axis) and square of radius (along $x-$ axis) of spherical body of density $\rho $ allowed to fall through a fluid of density $\sigma $ is a
A pan balance has a container of water with an overflow spout on the right-hand pan as shown. It is full of water right up to the overflow spout. A container on the left-hand pan is positioned to catch any water that overflows. The entire apparatus is adjusted so that it’s balanced. A brass weight on the end of a string is then lowered into the water, but not allowed to rest on the bottom of the container. What happens next?
