    A vessel with square cross-section and height of 6 m is vertically partitioned. A small window of 100 cm2100\text{ }cm^{2} with a hinged door is fitted at a depth of 3 m in the partition wall. One part of the vessel is filled completely with water and the other side is filled with the liquid having density 1.5×103 kg/m31.5 \times 10^{3}\text{ }kg/m^{3}. What force (in N) one needs to apply on the hinged door so that it does not get opened?(Acceleration due to gravity =10 m/s2= 10\text{ }m/s^{2} )
  4. Question 4

    The density and breaking stress of a wire are 6×6 \times 104 kg/m310^{4}\text{ }kg/m^{3} and 1.2×108 N/m21.2 \times10^{8}\text{ }N/m^{2} respectively. The wire is suspended from a rigid support on a planet where acceleration due to gravity is 13\frac{1}{3}rd of the value on the surface of earth. The maximum length of the wire without breaking is ______ mm (take, g=g = 10 m/s210\text{ }m/s^{2} )
