Question

27) A metal cuboid of mass M kg rests on a
table surface are of 40 cm in contact
with the table. The pressure exerted by
the cuboid on the table surface is 10000
Pa. Value of Mis (given that g=10 ms-2)
(a) 20 kg
(b) 5 kg
(c) 4 kg
(d) 2.5 kg​

Answer 1

Answer:

4 kg

Step-by-step explanation:

Area ⇒40 cm²

⇒40×10−²² m² ∵(²²=4)

Pressure ⇒10000 pa

Force⇒weight⇒mg

Force⇒Pressure×Area

mg=10000×40×10−²² m²

m⇒40/10

m⇒4kg
