(i) State the SI units of thrust and pressure.
(ii) In which situation, we exert more pressure on ground when we stand on one foot or on the both feet? Justify your answer.


#2

(i) The SI unit of thrust is newton (N). The SI unit of pressure is ${{Nm}^{-2}}$or pascal (Pa).
(ii) We exert more pressure on ground when we stand on one foot than the both feet, as the area of onefoot is half than that of two feet and p is inversely proportional to 1/A
