At a given place where acceleration due to gravity is $g{\rm{m}}{{\rm{s}}^{ - 2}},$ a sphere of lead of density $d{\rm{kg}}{{\rm{m}}^{ - 3}}$ is gently released in a column of liquid of density ${\rm{\rho kg}}{{\rm{m}}^{ - 3}}$. If $d > {\rm{\rho }},$ the sphere will

Fall vertically with an acceleration $g\left( {\frac{{d - {\rm{\rho }}}}{d}} \right)$

Fall vertically with an acceleration $g{\rm{m}}{{\rm{s}}^{ - 2}}$

Fall vertically with no acceleration

Fall vertically with an acceleration $g\left( {\frac{{\rm{\rho }}}{d}} \right)$

At a given place where acceleration due to gravity is

g\mathrm{m}{\mathrm{s}^{ - 2}},

a sphere of lead of density

d\mathrm{kg}{\mathrm{m}^{ - 3}}

is gently released in a column of liquid of density

\mathrm{\rho kg}{\mathrm{m}^{ - 3}}

. If

d > \mathrm{\rho },

the sphere will

View answer and explanation

Correct option: C

Fall vertically with an acceleration

g\left( {\frac{{d - \mathrm{\rho }}}{d}} \right)

Option C (Fall vertically with an acceleration

g\left( {\frac{{d - \mathrm{\rho }}}{d}} \right)

) is correct because the net acceleration is the difference between gravitational acceleration and the acceleration due to buoyancy.
