Answer : The force exert to accomplish this is, 23.8 N
Explanation :
The formula used for force is:
[tex]F=P\times A[/tex]
where,
F = force
P = pressure
A = area
Given:
Pressure = [tex]115mmHg=15332.03Pa[/tex]
conversion used : (1 mmHg = 133.322 Pa)
Area = [tex]15.5cm^2=15.5\times 10^{-4}m^2[/tex]
conversion used : [tex](1cm^2=10^{-4}m^2)[/tex]
Now put all the given values in the above formula, we get:
[tex]F=(15332.03Pa)\times (15.5\times 10^{-4}m^2)[/tex]
[tex]F=23.8N[/tex]
Thus, the force exert to accomplish this is, 23.8 N
