A cylindrical capillary tube of 0 2 mm radius is made by joining two capillaries T and T of different materials having water contact angles of 0 and 60 respectively The capillary tube is dipped vertically in water in two different configurations case I and II as shown in figure Which of the following option s is are correct Surface tension of water 0 075 N m density of water 1000 kg m take g 10 m s Case I T2 T1 Case II T1 T2 A For case II if the capillary joint is 5 cm above the water surface the height of water column raised in the tube will be 3 75 cm Neglect the weight of the water in the meniscus B For case I if the joint is kept at 8 cm above the water surface the height of water column in the tube will be 7 5 cm Neglect the weight of the water in the meniscus C For case I if the capillary joint is 5 cm above the water surface the height of water column raised in the tube will be more than 8 75 cm Neglect the weight of the water in the meniscus D The correction in the height of water column raised in the tube due to weight of
