Question

The radius of a truncated cone increases linearly with its length from 10cm to 20cm respectively. Given length of object is 50 cm. If the thinner end is taken at r=0, the value of x at which radius becomes zero is​

Answer 1

Answer:

A glass capillary tube is of the shape of truncated cone with an apex angle α so that its two ends have cross sections of different radii. When dipped in water vertically, water rises in it to a height h, where the radius of its cross section is b. If the surface tension of water is S, its density is ρ, and its contact angle with glass is θ, the value of h will be (g is the acceleration due to gravity)
