20\,\text{cm}

above the mercury–water interface. How much higher will the mercury level stand in the right limb compared to the left limb? (Density of mercury

=13.6\times10^{3}\,\text{kg\,m}^{-3}

; density of water

=1.0\times10^{3}\,\text{kg\,m}^{-3}

.) (a)

0.75\,\text{cm}

(b)

3.0\,\text{cm}

(c)
