Question

A rectanguler wooden block mass of 4kg the length and breadth and height of then =50,10,15 and find the pressure of table top. (1) When wooden is kept with its surface measuring 50×25cm . (2) When the wooden block kept with its surface measuring 25×10cm on the table

Answer 1

Answer:

Explanation:

F=W=m.g

F=W =4×10(considering g as 10)

F=W =40N

a)

P= F/A

P=40N/50CM×25CM

​P=40N/1250cm ²

​P=40N/0.125m²

P=320 N/m² (Pa)

b)

P=40N/25cm×10cm

P=40N/250cm²

P=40N/0.025m²

P=1600N/m²
