Four workshop machines stand on rubber feet. The table gives the normal force that one foot of each machine exerts on the floor and the contact area of that foot.
| Machine | Force in N\mathrm{N}N | Area in cm2\mathrm{cm^2}cm2 |
|---|---|---|
| K | 150 | 30 |
| L | 210 | 30 |
| M | 200 | 50 |
| N | 270 | 45 |
Which option lists the machines in order of the pressure under one foot, from greatest to least?
M, K, N, L
L, N, K, M
N, L, M, K
L, K, N, M
