Question

Atmospheric pressure at sea level is approximately equal to ________

• A. ${10}^{5}N/m^2$
• B. ${10}^{7}N/m^2$
• C. ${10}^{3}N/m^2$
• D. ${10}^{1}N/m^2$

Answer 1

The correct option is A ${10}^{5}N/m^2$

Atmospheric pressure at sea level is defined as 1 atm which is equivalent to ${10}^5$ Pascal

i.e., 1 atm = ${10}^{5}N/m^2={10}^5$ Pascal.
