Question

a block of glass is kept on a wooden board the mass of the glass block is 2kg and its dimension are 8cm,5cm,1cm,find the pressure exerted by the glass block on wooden board if its made to lie on the board with dimensions

5cmm,1cm

8cm,5cm

Answer 1

Case 1 : 5cm × 1cm
Pressure= Force /Area
= 2(10) / 5×1
= 20/5 = 4 N/cm²

Case 2 : 8cm × 5cm
P = F/A
= 2(10)/8×5
= 20/40 = 0.5 N/m²

Answer 2

hi there,
1.p=f/a
f=ma=2*10=20 (g=10)
area=5
pressure=20/5=4Pa
2.area=40
pressure=20/40=1/2=.5 N/cm^2
i hope this helps u nd pls smash th ethanks button
