Can you please solve question no 6full

Q6. (a) A boy weighs 50 N. The area of contact of his two feet is 10 cm2. What pressure does he exert on the ground if he stands on one foot?
(b) A man weighs 250 N. Suppose he stands on a pointed edge with base area 5 cm2? How much pressure does he exert on the ground?
(c) Now compare (1) and (ii) to find out the following.
(i) Who exerts more force on the ground, the boy in (i) or the man in (ii)?
(ii) Who exerts greater pressure on the ground, the boy or the man?
(iii) Who is likely to sink into the ground, the man standing on a pointed edge or the boy standing on one foot and why?

Dear Student,

We know, pressure = forcearea(a) As the boy stands on one foot, the area of contact = 102 = 5 cm2Thus, the pressure = 505 = 10 N/cm2 (b) Pressure exerted by the man = 2505 = 50 N/cm2
For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.
