an open U-tube contains mercury . when 13.6 cm of water is poured into one of the arms of the tube , then the mercury rise in the othe arm from its initial level is
ans: 0.5cm
why not 1cm
13.6cm water equals added 13.6/13.6=1cm mercury
so the mercury rise 1cm/2=0.5cm as on both side.
so the mercury rise 1cm/2=0.5cm as on both side.
