Answer» ⭐《ANSWER》 ↪Actually WELCOME to the concept of the FORCE AND PRESSURE ↪Basically here , we are DEALING with the Normal pressure exerted by a object ( square) on its RESPECTIVE base, ↪Since here , the Object dimension is a SQAURE , so we get as , 〽Pressure = Force / AREA , ↪Since here , the pressure is normal to base , also the force is normal to base , thus ↪Force = MG ( g = acceleration due to gravity = 10 m/s^2) ↪so we get as , ↪F = (0.75)(10) ↪F = 7.5 N ↪now the base area , will be as , ↪Area = (side)^2 ↪Area = (0.1)^2 m^2 ↪Area = 0.01 m^2 ↪so now here , ↪PRESSURE = 7.5/0.01 〽P = 750 pa ↪Since here , the SI UNIT of pressure is N/m^2 or Pascals or Pa ↪so we get as , ⭐PRESSURE ON THE BASE = 750 Pa |
