Answer 1

QUESTION:-

"what is force due to atmospheric pressure on a head of area 15 cm × 15 CM ?

TO FIND:-

FORCE OF ATMOSPHERIC PRESSURE ON A HEAD OF 15 CM × 15 CM

GIVEN:-

AREA OF HEAD

EXPLANATION:-

AREA OF HEAD = 15 cm× 15 cm=225 cm²===>225×10⁻⁴ m²

AS WE KNOW ,

1 atm=10⁵ Pascals

WE KNOW THAT :-

10⁵ pa=F/225×10⁻⁴ m square

F= 10⁵Pa ×225×10⁻⁴ m square

10⁵N/ m²×225×10⁻⁴ m²

ON CALCULATING IT WE GET,

F=2250 N

HENCE, THE FORCE WILL BE OF 2250 NEWTON
