A rectangular vessel is filled with water and oil in equal proportion (by volume), the oil being twice lighter than water. Show that the force on ach side wall of the vessel will be reduced by one fifth it the vessel is filled only with oil. (Assume atmospheric pressrue is negligible)

A cylinderical vessel is filled with water up to height H. A hole is bored in the wall at a depth h from the free surface of water. For maximum range h is equal to

A vesse of depth x is half filled with oil of refractive index mu_(1) and the other half is filled with water of refrative index mu_(2) . The apparent depth of the vessel when viewed above is

A vesse of depth x is half filled with oil of refractive index mu_(1) and the other half is filled with water of refrative index mu_(2) . The apparent depth of the vessel when viewed above is

A wide cylindrical vessel 50cm in height is filled with water and rests on a table. Assuming the viscosity to be negligible, find at what height from the bottom of the vessel a small hole should be perforated for the water jet coming out of it to hit the surface of the table at the maximum distance l_(max) from the vessel. Find l_(max) .
