Final answer:
The pressure exerted is calculated to be 10 N/m² or 10 Pascals (Pa), using the formula for pressure P = F / A with the given force and area.
Step-by-step explanation:
To calculate the pressure exerted by a force of 300N acting normally on an area of 30m2, we should use the formula for pressure, which is defined as force per unit area: P = F / A, where P is pressure, F is force, and A is area. Substituting the given values, we have P = 300N / 30m2.
After performing the division, we find that the pressure exerted is 10 N/m2, which can also be expressed as 10 Pascals (Pa) since 1 Pa is equal to 1 N/m2.
