MHT CET 2025 Physics question
When one end of the capillary is dipped in water, the height of water column is 'h'. The upward force of 108 dyne due to surface tension is balanced by the force due to the weight of water column. The inner circumference of the capillary is (surface tension of water = 7.2 x 10 N/m )
Answer: (D)
Solution
The upward force due to surface tension is . Surface tension N/m 10^{-2}\frac{10^5\ dyne}10^2$\
