A nail has 2metre square at one end,1/100m^2 and at the other end. a force of 1000g. weight is applied on the first end calculate the pressure avthing on the wall? Value of g=10m/sec^2

The area of first end of nail is 2 m2
Area of other end is 1/100 = 10-2 m2 = 0.01 m2
Force applied = 1000 gwt = 1000 × 10 = 10000 N ...(Since, g =10 m/s2)
Pressure is applied at first end. This means other end whose area is 0.01 m2 is in contact with the wall.
Thus, the pressure acting on a wall is
P = Force/ Area = 10000/0.01 = 1000000= 106 N/m2
