Question
pressure=(101ce)/(area) A block exerts a force of 5 N on the ground. Calculate the pressure the block exerts on the ground , in N/m^2 , when it is a) flat on the ground, so that the area of its base is 0.04m^2 b) standing up on its side, so that the area of its base is 0.025m^2

After calculating the above equations, we get:
and
.
Explanation
## Step1:We are given the force a block exerts, its base areas in two different positions, and we need to calculate the pressure in both conditions. The definition of pressure is the force applied per unit area. The mathematical representation is:###
where:-
represents the force (in Newtons),-
represents the area (in square meters), and-
represents the pressure (in Pascal, which is
).## Step2: When the block is lying flat on the ground, its base area is
. Using the above formula, we substitute
and
:###
## Step3:During the third step, calculate the pressure when the area is
. Likewise like in step 2, substitute
and
