(density of iron =7.8xx10^(3) kg//m^(3) , density of mercury =13.6xx10^(3) kg//m^(3) , density of water =10^(3) kgm^(3) )(Neglect the atmospheric pressure) Time period of small oscillations of block is

Water rises up in a glass capillary upto a heigh 10 cm, while mercury falls down by 3.5 cm in the same capillary. If the angles of contact for water-glass and mercury-glass are taken as 0^(@) and 135^(@) respectively, compare the surface tensions of water and mercury. [Given density of water = 10^(3) kg m^(-3) , density of mercury = 13.6 xx 10^(3) kg m^(-3) ]
