Answer 1

$\huge\boxed{\mathtt\red{Correct\: Question:-}}$

✪ A body of mass 1200 gram rests on a surface area of 10 m².Find the pressure acting on the surface in pascal. (Take g = 10 m/s²)

$\large\boxed{\mathtt\red{Given :-}}$

◑ Mass of the body = 1200 grams = 1.2 kg

◑ Surface Area of the body = 10 m²

$\large\boxed{\mathtt\red{To\:Find:-}}$

✏ Pressure acting on the surface in Pascal (pa).

$\large\boxed{\mathtt\red{Solution:-}}$

we know that ,

$\small\boxed{\mathtt\blue{Force = mass×acceleration}}$

where,

• acceleration = (here) due to gravity (10 m/s²)

Applying the formula :-

⟹ Force = 1.2 kg × 10 m/s²

∴ Force = 12 N

Now, we have :-

• Force = 12 N

• Area = 10 m²

Applying the formula of Pressure :-

$\large\boxed{\mathtt\blue{Pressure=\frac{Force}{Area}}}$

✒ Pressure = $\large{\mathtt{\frac{12\:N}{10\:m²}}}$

∴ Pressure = 1.2 N/m²

we know that :-

• 1 N/m² = 1 pa

$\large\boxed{\mathtt\green{∴The\: pressure \:acting \:on\: the\: surface \:is \:1.2\:pa}}$
