Question

A rectangular solid block has length 10cm breadth 5cm and height 2 cm. If it has on a horizontal surface and has density 1000kgm-3. Calculate the pressure it exerts on the surface.

Answer 1

Answer:

sorry friend I don't know what is the answer of this question

Answer 2

Answer:

Given that,

density of water (ρ)=10

3

Kg/m

3

water fixed up till height (h)=2 m

Area of base (A)=100 m

2

.

assuming atmospheric pressure (P

0

)=1 atm≃10

5

Pa

so, pressure at bottom of tank,

P=P

0

+ρgh.

=10

5

+10

3

×10×2[g=10 m/s

2

]

P=(1.2×10

5

) Pa

Thus, thrust on bottom surface,

F=P.A=(1.2×10

5

)×10

⇒F=1.2×10
