A tank of base area `4 m^2` is initially filled with water up to height 2m. An object of uniform cross-section `2m^2` and height 1m is now suspended by wire into the tank, keeping distance between base of tank and that of object 1m. Density of the object is 2000kg/`m^3`. Take atmospheric pressure `1xx10^5 N//m^2 , g = 10m//s^2`.

The downwards force exerted by the water on the top surface of the object is
