| Use:\[\text{Pressure} = \frac{\text{Force }(\text{N})}{\text{Area }(\text{cm}^2)}\] |
The base of a filing cabinet is a rectangle. It measures 45 cm by 60 cm.
The whole of the base is in contact with the horizontal ground.
(a)
The empty filing cabinet exerts a force of 675 N on the ground.
What is the pressure exerted on the ground by the empty filing cabinet?
Give your answer in N/cm2. [2]
(b)
When the filing cabinet is full, the pressure it exerts on the ground is 0·75 N/cm2.
What is the force that the full filing cabinet exerts on the ground?
Give your answer in newtons (N). [2]
