If percentage
uncertainty in the force and area are 2% and 5% respectively then what will the
be percentage uncertainty in pressure exerted by the force on the area?
a) 2%
b) 5%
c) 7%
d) 3%
Explanation: To calculate the percentage uncertainty in pressure exerted by the force on the area, we can use the formula:
Percentage uncertainty in pressure = Percentage uncertainty in force + Percentage uncertainty in area
Given: Percentage uncertainty in force = 2% Percentage uncertainty in area = 5%
Plugging in these values into the formula, we get:
Percentage uncertainty in pressure = 2% + 5% Percentage uncertainty in pressure = 7%
The percentage uncertainty in pressure exerted by the force on the area is 7%.
