Two boys X and Y each have the same total weight and are standing on soft ground. Which boy is more likely to sink into the soft ground and why?
Answers
Boy X covering less area is more likely to sink.
Step-by-step explanation:
Pressure is the force exerted on a surface divided by the area over which its applied
Pressure = Force / Area
Both boys have same weight hence force exerted by both of them is equal
Person is more likely to sink who exerts more pressure
Pressure = Force / Area
For a given force is inversely proportional to area
Pressure ∝ 1/ Area
Boy who is covering less area is more likely to sink.
Hence Boy X covering less area is more likely to sink.
