A cylindrical vessel filled with water upto a height of 2m stands on a horizontal plane. The side wall of the vessel has a plugged circular hole touching the bottom. Find the minimum diameter of the hole so that the vessel begin to move on the floor, if the plug is removed. The coefficient of friction between the bottom of the vessel and the plane is 0.4 and total mass of water plus vessel is 100kg.
The monkey B shown in figure is holding on to the tail of the monkey A which is climbing up a rope. The masses of the monkeys A and B are 5kg and 2kg respectively. If A can tolerate a tension of 30N in its tail, what force should it apply on the rope in order to carry the monkey B with it? Take $g = 10m/s^2$​​​​​​​

From a certain apparatus, the diffusion rate of hydrogen has an average value of $28.7 \mathrm{~cm}^3 \mathrm{~s}^{-1}$. The diffusion of another gas under the same conditions is measured to have an average rate of $7.2 \mathrm{~cm}^3 \mathrm{~s}^{-1}$. Identify the gas. [Hint: Use Graham's law of diffusion $\frac{\mathrm{R}_1}{\mathrm{R}_2}=\left(\frac{\mathrm{M}_2}{\mathrm{M}_1}\right)^{\frac{1}{2}}$, where $\mathrm{R}_1, \mathrm{R}_2$ are diffusion rates of gases 1 and 2 , and $\mathrm{M}_1$ and $\mathrm{M}_2$ their respective molecular masses. The law is a simple consequence of kinetic theory]
