Question

A block of mass 3 kg and dimension 1m × 2m × 3m rest on the floor. Find the maximum pressure exert
by the block on the floor is – (g = 10 m/s2
)

Answer 1

Maximum pressure is 15N/m2

Answer 2

Answer:

P=5 N/m^2

DATA:

Mass=3kg

Dimension= 1m, 2m, 3m,

g= - 10m/s^2 (against the gravity)

SOLUTION:

first mass multiply by gravity

so

3kg ×-10 = -30

now

Dimension of the floor is 1m, 2m, 3m,

2m×3m =6m^2

P=F/Aardvark

P=-30N/6m^2

P= -30/6 :N/m^2

P=-5N/m^2

_______________________________________

now for faver of gravity

DATA:

Mass=3kg

Dimension =1m, 2m, 3m,

g=10m/s^2

Solution:

mass ×gravity

3kg×10m/s^2 =30N

Dimension of floor is= 1m, 2m, 3m,

2m×3m =6m^2

P= F/A

p= 30N/6m^2

P= 30/6 ;N/m^2

P=5N/m^2

hopefully it is correct and helpful for you
