Question

A wooden cylinder floats in water such that $4cm$ of it is above water, if the same cylinder is made to float in alcohol (density $0.8g{m}^{-3}$), the length of cylinder above alcohol will be

• A. $4cm$
• B. more than $4cm$
• C. less than $4cm$
• D. none of these

Answer 1

The correct option is C less than $4cm$

C. less than 4cm
Because more volume of alcohol needs to be displaced to displace the equal weight of water. since density of alcohol is lesser.
