Question

Calculate the pressure exerted in the following cases-

a) A girl of 40 kg wearing heels with an area of cross section 5 metre square.

b) A cow of 80 kg with foot area each of 10 metre square. (1 kg wt =10N) Choose the correct statement from the following.Required to answer. Single choice.

pressure exerted by the girl is more.

pressure exerted by the cow is more.

Both exert equal pressure.

Both exert no pressure​

Answer 1

Answer:

a) Pressure = $\frac{40}{5}$

                   = 8 Pa

b) Pressure = $\frac{80}{10}$

                    = $\frac{8}{1}$

                    = 8 Pa

∴ The pressure exerted by the girl and the cow is the same.
