(chatquestion)...Pre-Medical : Physics ALLEN 75. lfa capillary of radiusris dipped in water, the height 82. Water rises to a height h in a capillary at the suf of earth. On the surface of the moon the heightdi water columm in the the same capillary wil be ALLEN of water that rises in it is h and its mass is M. If the क radius of the capillary is doubled the mass of water that rises in the capillary will be thai (1) 4M (1) 6h (2) 1/6 h (2) 2M (3) h 91. (4) Zero 83 On dipping a capillary of radius 'r' in water, water rises upto a height H and potential energy of water is u,. If a capillary of radius 2r is dipped in water, (3) M Shape of meniscus for a liquid of zero angle of (4) suftsce S contact is (1) plane (2) parabolic (3) hemi-spherical 84. Due to capillary action a liquid will rise in a tube if is (4) cylindrical then the potential energy is u,. The ratio angle of contact is (1) 2:1 (2) 1:2 (3) 4:1 (4) 1:1 (1) acute (2) obtuse 92 The m of sa 7 A vessel, whose bottom has round holes with diameter of 0.1 mm, is filled with water. The 85. Two droplets merge with each other and fom a maximum height to which the water can be filled without leakage is :- (3) 90° (4) 180° come large droplet. In this process: the (1) Energy is liberated (S.T. of water = 75 dyne/cm, g = 1000 cm/s") (2) Energy is absorbed 13 (1) 100 cm (2) 75 cm (3) 50 cm (4) 30 cm (3) Neither liberated nor absorbed 93. 78. Ina surface tension experiment with a capillary tube water rises up to 0.1 m. If the same experiment is 86. Two capillary tubes of same diameter are put (4) Some mass is converted into energy whose relative...(q76)
