Why is there excess pressure always on the concave side or surface of the meniscus? In my book it is also written that excess pressure balance the vertical resultant forces due to surface tension. How can a pressure balance a force? My teacher said that shape of meniscus does not depend on vertical component of force. Which force is she talking about? Why doesn't the shape of meniscus does not depend on vertical force as there are also curved meniscus so shouldn't vertical force should have some role to play in the curved surface?
