Question

calculate the pressure exerted by a body of 2 kg over an area of 5 sq.cm ?

Answer 1

$\huge\text{\underline{Answer}}$

Mass of body = 2 Kg

area = 5Cm^2.

In m = 0.0005 m^2.

Now,pressure :- The force applied per unit area is known as pressure.

F = m× g (g = 10 m/s^2)

F = 200 × 10

F = 2000 N

From definition,

$\boxed{\sf{P = \frac{F}{a} }}$

$\implies$ $p = \frac{ 2000 }{0.0005}$

$\implies$ $p = \frac{2000 \times 10000}{5}$

$\implies$ $p = 400 \times 10000$

$\implies$ $p = 4 \times {10}^{6} p$

The pressure exerted by body is 4 × 10^6 pascal.
