1.	5. The following observations were take fordetermining surface tension of water bycapillary tube method. Diameter of capillar,D=125x10-2m and rise of water incapillaryh=1.46 x 10-2m.Taking g=9.80ms-2 and using therelationT=(rgh/2) x 103Nm"?, what is the possibleerror in surface tension T?(a) 2.4%(b) 15%(c) 1.6%(d)0.15%
Answer» Answer: The force of surface tension on a ring SITUATED on the surface of WATER is 14π×10^-4N. Then the diameter of the ring is (surface tension of water = 70×10^-3 N/m) a) 5 mm b) 1 cm c) 2 cm d) 4 cm plz.solve & explain it..
