(a) 20 Pa ; (b) 40 Pa
Explanation:
Pressure can be calculated using the formula:
Pressure = force/area units
Area is typically measured in units of meters squared (m2). Since pressure is calculated by dividing force by area, it has units of Newtons per meter squared (N/m2) or Pascals (Pa).
(a) Pressure = 200 / 10 = 20 N/m2 = 20 Pascals.
(b) Pressure = 200 / 5 = 40 N/m2 = 40 Pascals.
