Q3) Mercury has a contact angle equal to (1400) with glass. A narrow (4mm) capillary tube made of this glass was dipped into a basin containing tulips. By how much does the mercury in the tube drop or rise relative to the surface of the liquid outside? Note that the surface tension of mercury (N/m 0.456); The density of mercury (13600 kg/m)
