Question

A rectangular wooden piece weighs 25 N. If it is placed in such a way that its
25cm length and 10 cm width are in contact with a surface, what will be the pressure
exerted by it on the surface?​

Answer 1

$pressure = \frac{force}{area \: per \: meter}$

given,

force = 25N

area = 25×10 = 250cm²

250cm² in meter = 0.025m²

by applying the formula,

$pressure = \frac{25}{0.025}$

$= \frac{25 \times 100}{25}$

= 100 Pascal

Weight is a type of force

as weight = mass × gravity acceleration
