A cylindrical container of radius `'R'` and height `'h'` is completely filled with a liquid. Two horizontal `L`-shaped pipes of small cross-sectional area `'a'` are connected to the cylinder as shown in the figure. Now the two pipes are opened and fluid starts coming out of the pipes horizontally in opposite directions. Then the torque due to ejected liquid on the system is

Choose the correct option: Water is filled in a cylindrical container to a height of 3m . The ratio of the cross-sectional area of the orifice and the beaker is 0.1 . The square of the speed of the liquid coming out from the orifice is (g=10m//s^(2)) .

A uniform rod of maass m and length L is placed on the fixed cylindrical surface of radius R at an small angular position theta from the vertical (vertical means line joining centre and vertex of the cylindrical path) as shown in the figure and released from rest. Find the angular velocity omega of the rod at the instant when it crosses the horizontal position (Assume that when rod comes at horizontal position its mid point and vertex of the circular surface coincide). Friction is sufficient to prevent any slipping.
