1.	A vertical U - tube of uniform cross - section contains water in both the arms. A 10 cm glycerine column (R.D. = 1.2) is added to one of the limbs. What is the level difference between the two free surface in the two limbs?
Answer» Solution :Let the DIFFERENCE between TWO limbs be x PRESSURE on the line Y, should be same below both limbs, so `rho_("glycerine")xxg xxh=rho_("WATER")xx(h+x)` `RARR 1.2xx10=1xx(h+x)` `rArr 2cm=x`
