A liquid rises to 15cm in a thin capillary. The radius of curvature of the liquid's surface (in th capillary) is 1mm.Now, the capillary is cut at a the 7cm mark.

    I think that now users will need google accounts to post comments.

    If you don't have one, creating one should take 5 minutes.

    If there are problems still, e-mail me at anuj.kalia11@imperial.ac.uk ;).
