1.	A long cylinder is fitted with a top on its wall at its lower end. Keeping the top closed, the cylinder is filled with water. Now the cylinder is made to float by placing it over a cork and then the tap is opened. State what will happen.
Answer» Solution :DUE to the lateral pressure of water, it will be seen that a jet of water COMES out through the opening of the TAP. If the opening of the tap is in the horizontal direction, then the water-jet will come out horizontally. Due to an equal but OPPOSITE reaction of this thrust, the cylinder (floating on the cork) will MOVE in the opposite direction.
