Telangana Board Solutions for Chapter: Floating Bodies, Exercise 2: Exercise 2

A solid sphere has a radius of $2 \mathrm{cm}$ and a mass of $0.05 \mathrm{kg}$. What is the relative density of the sphere?

A small bottle weighs $20 \mathrm{g}$ when empty and $22 \mathrm{g}$ when filled with water. When it is filled with oil it weighs $21.76 \mathrm{g}$. What is the density of oil?

An ice cube floats on the surface of water filled in glass tumbler (density of ice$=0.9 \mathrm{g} {\mathrm{cm}}^{-3}$). Will the water level in the glass rise when the ice melts completely?

Find the pressure at a depth of $10 \mathrm{m}$ in water if the atmospheric pressure is $100 \mathrm{kPa}$. $\left[1 \mathrm{Pa}=1 \mathrm{N} {\mathrm{m}}^{-2}\right]\left[100 \mathrm{kPa}={10}^5 \mathrm{Pa}={10}^5 \mathrm{N} {\mathrm{m}}^{-2}=1 \mathrm{atm}\right]$
