Question

A cubic lump of cheese of area 10 cm x
10 cm and weight 3 N stands on a table.
Calculate the pressure (in pascal Pa)
exerted by it on the tabl

Answer 1

Answer:

Area = 3cm×3cm=9cm

2

=9×10

−4

m

& Pressure exterted = 5Pa

Since Pressure =

Area

Force

Force = Pressure × Area

Force = 9×10

−4

×5N

= 45×10

−4

N.
