Question

A body weighing 5 kgf placed on a surface area on 0.1 metre square exerts a thrust on the surface :
a. 50 kgf
b. 5 kgf
c. 50 kgf metre square
d. 5 kgf metre square ​

Answer 1

Answer:

50 pas or 50kgf m^(-2)

Explanation:

Thrust = force / area

Here,

Force = weight = 5 kgf

Area = 0.1 m^2

Thus,

= > thrust = 5 kgf / 0.1 m^2

= > thrust = 50 kgf m^(-2)

Unit of pressure(thrust) is pascal.

Thrust = 50 pas or 50kgf m^(-2)

Answer 2

Answer:

pressure= thrust/ area

thrust= weight of the body.

so, the body exerts 5 kgf on the surface of the area.option no.(b)
