A) \[\frac{2T}{r}\]
B) \[\frac{T}{r\cos \theta }\]
C) \[\frac{2T\cos \theta }{r}\]
D) \[\frac{T\cos \theta }{r}\]
Correct Answer: C
Solution :
When a capillary tube is dipped in water, the water meniscus inside the tube is concave. The pressure just below the meniscus is less than the pressure just above it by \[\frac{2T}{R},\] where T isYou need to login to perform this action.
