Hi, in this question we are having two parts.
00:02
In the first part of the question we are given that equal amounts of water is poured into glass tubes.
00:09
We are having the diameters given here in this manner, 25mm, 10mm and 5mm.
00:15
We are asked to choose the glass tube in which there is largest capillary rays.
00:22
Here we can say that the height of tube is inversely proportional to its radius.
00:32
Higher the radius, lesser will be the height or we can say that the lesser will be the capillary raise here.
00:41
We know that the radius is twice of diameter.
00:47
Here we can see in 25 mm the radius will be equal to 2 into 25, that is 50mm.
00:58
In the second one we can see radius will be 2 into 10.
01:03
The 20 mm and in third one the radius will be 2 into 5 that is the 10 mm we can see that the maximum radius is present in the first glass tube that is 50 m therefore higher the radius least will be the capillary raise whereas in the 5mm we can see we have the least radius therefore it will be having the largest capillary raise hence we can say that the correct answer will be 5 m in which there will be the largest capillary rays...
