Question

the pressure exerted by 50 kg(g=10 m/s² ) on an area of cross section of 2 m² is:​

Answer 1

$\text{Given the mass of the object is 50kg}$

$Area\:of the\:cross\:section = 2m^{2}$

$Acceleration\:due\:to\:gravity = 10m/s^{2}$

$\bold\red{\boxed{Thrust = mass \times acceleration}}$

$\bold\blue{\boxed{Thrust = 50kg \times 10m/s^{2}}}$

$\bold\blue{\boxed{Thrust = 500 N}}$

______________________________________

$\bold\red{\boxed{Pressure = \dfrac{Thrust}{Area}}}$

$\bold\blue{\boxed{Pressure = \dfrac{500N}{2m^{2}}}}$

$\bold\blue{\boxed{Pressure = 250N m^{2}}}$

Answer 2

Explanation:

Given the mass of the object is 50kg

Area\:of the\:cross\:section = 2m^{2}Areaofthecrosssection=2m

2

Acceleration\:due\:to\:gravity = 10m/s^{2}Accelerationduetogravity=10m/s

2

\bold\red{\boxed{Thrust = mass \times acceleration}}

Thrust=mass×acceleration

\bold\blue{\boxed{Thrust = 50kg \times 10m/s^{2}}}

Thrust=50kg×10m/s

2

\bold\blue{\boxed{Thrust = 500 N}}

Thrust=500N
