10. Pressure exerted by a block

A block is kept on a tabletop. The mass of the block is 45 kg, and its dimensions are \(40\) \(cm\) \(×\) \(20\) \(cm\) \(×\) \(10\) \(cm\). Find the pressure exerted by the wooden block on the tabletop if made to lie on the tabletop with its sides of dimensions

(a) \(20\) \(cm\) \(×\) \(10\) \(cm\)

(b) \(40\) \(cm\) \(×\) \(20\) \(cm\).

(Take \(g\) \(=\) \(10\) $m/s^2$)

 

  

Answer:

a)The pressure exerted by the block is$N/m^2$
