Answer 1

Answer:

pressure= 20 pascal

Explanation:

here in the question given that solid body weighs 100N,....so here the force on wooden plank is 100N

area of contact is given as 5m²

pressure= force / area of contact

pressure=100N/5m²

pressure= 20pascal

(therefore pascal is the SI unit of pressure)

hope u understand well
