Question

A metal cuboid of mass M kg rests on a table surface area of 40_sq. in contact with the table. The pressure exerted by the cuboid on the table surface is 10000 Pa. Value of M is (given that g=10_-sq.)
(a) 20 kg
(b) 5 kg
(c) 4 kg
(d) 2.5 kg

In this que also, the unit of area is not give......that's why I'm confused.....plzzzz.....ans this​

Answer 1

Answer:

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
