MHT CET 2022 Physics question
If a capillary tube of radius 1 mm is immersed in water, the mass of water rising in the capillary tube is 'm'. If the radius of the capillary tube is doubled, then the mass of water that rises in the same capillary tube will be
Answer: (D)
Solution
The height of capillary rise is . The mass of the raised column is , so (it equals the surface tension force $2π
