A block of weight 5kgf and dimensions 5cm * 2cm *1 rests on a table in three different positions with its base as (i) 5cm *2 cm (ii) 2cm * 1cm (iii) 1 cm *5 cm . Calculate the maximum and minimum pressure in S.I units exerted by a block on its base

Answer:
Pressure is the force per unit area. So, P=F/A
Thus, minimum surface area (5cm×10cm) will give the maximum pressure and maximum area (20cm×10cm) will give the minimum pressure.
So, P
max
=
50×10
−4
2g
N/m
2
and P
min
=
200×10
−4
2g
N/m
2
Thus,
P
max
P
min
=50/200=1/4
