Question

26. What will be the pressure when 30 N
force is applied on 120 cm area?
(a) 2.5 x 10' N/m (b) 5 x 10' N/m
(c) 25 x 10' N/m (d) 5 x 10' N/m​

Answer 1

Answer:

Pressure = 25 x 10^2 N/m

Step-by-step explanation:

Pressure = Force/Area

Area = 120cm^2 = 120 x 10^-4 m^2

[1cm = 1/100m    1cm^2 = 1/(100x100) m^2]

Pressure = 30N/120x10^-4

= 30 x 10^4 / 120 = 2500N/m

Pressure = 25 x 10^2 N/m
