Question

The angle of contact between glass and water is 0^ and water rises in a glass capillary upto 6 cm (Surface tension of water is T). Another liquid of surface tension ' 2 ~T ^ , angle of contact 60^ and relative density 2 will rise in the same capillary up to ( 0^ =1, 60^ =0.5 )

Quantrex Academy · Accepted Answer

Correct answer: C. 3 cm

h = 2 ~T r g For water: array r 6= 2 T (0) r 1 g r= 2 T 6 g = T 3 g array For other liquid: h= 4 ~T 60 r 2 g = 4 ~T 0.5 ~T 3 ~g 2 g =3 ~cm

The angle of contact between glass and water is 0^ and water rises in a glass capillary upto 6 cm (Surface tension of water is T). Another liquid of surface tension ' 2 ~T ^ , angle of contact 60^ and relative density 2 will rise in the same capillary up to ( 0^ =1, 60^ =0.5 )
