At a given place where acceleration due to gravity is `g` `m//sec^(2)`, a sphere of lead of density `d` `kg//m^(3)` is gently released in a column of liquid of density `'rho' kg//m^(3)`. If `d gt rho`, the sphere will

A

Fall vertically with an acceleration ‘g’ m/se`c^2`

B

Fall vertically with no acceleration

C

Fall vertically with an acceleration `g((d-p)/d)`

D

Fall vertically with an acceleration `g(p/d)`

Text Solution

Verified by Experts

The correct Answer is:
C
Apparent weight = actual weight – upthrust force
`Vdg.=vdg-Vpg`
`rArrg.=((d-p)/d)g`
