Question

Q10. a body of mass 50 kg kept on horigantal surface with
area of contact 5m^2 then pressure (g=10m/se^2) is
A 100 pa
B 50 pa.
C 20 pa

D none. ​

Answer 1

Answer:

100 pa is crct

Explanation:

refer to the attachment above

Answer 2

Given:-

• Mass of body (m) = 50kg

• Area of contact (a) = 5m²

• Acceleration due to gravity (g) = 10 m/s²

To Find :-

• Pressure (P)

Solution:-

We haven to calculate the pressure actings on the surface. Firstly we have to find the force acting on the body .

⟹ Force = Mass × Acceleration

⟹ F = m×a

⟹ F = 50 × 10

⟹ F = 500 N

As we know ,

⟹ Pressure = Force/Area

⟹ P = F/a

⟹ P = 500/5

⟹ P = 100 Pascal

Thus, the pressure = 100 Pa

Hence, Option (a) is the correct answer.
