1.	A long capillary tube is dipped in water. The water rises up to certain height. What happens to the water colnmn in the capillary, if the entire arrangement is placed in a freely falling elevator?
Answer» Solution :`h=(2scostheta)/(rrhog)`. During free fall, the arrangment is in a STATE of WEIGHTLESSNESS. Effective acceleration G - a = 0. So WATER will rise to fill the entire tube.
