Question

A block of mass of a 2 kg with dimensions $5cm\times 20cm\times 10cm$ respectively. The ratio of maximum to minimum pressure it exerts on the change in orientation is :

• A. 1 : 1
• B. 1 : 2
• C. 1 : 4
• D. 4 : 1

Answer 1

The correct option is D 4 : 1

$M=2kg$
Maximum base area
$=20cm\times 10cm=200c{m}^2$
Minimum base area
$=5cm\times 10cm=50c{m}^2$
$\frac{P_{max}}{P_{min}}=\frac{\text{Maximum base area}}{\text{Minimum base area}}$
$=\frac{200}{50}=4:1$
