the dimensions of a rectangular block of mass 10 kg kept on a table are 0.2 by 0.1 by 0.05 m3, find the pressure exerted by the block if it is kept on the table with sides of dimensions : (i) 0.2 by 0.1 m2  and  (ii) 0.1 by 0.05 m2 ?( g = 10 m/s2)

Dear Student,

Please find below the solution to the asked query:

Weight of the block is $10\times 10=100 \text{N}$
(i) Pressure is $\frac{100}{0.2\times 0.1}=5000 {\text{Nm}}^{-2}$
(ii) Pressure is $\frac{100}{0.1\times 0.05}=0.0002 {\text{Nm}}^{-2}$
