Question

A Rectangular Wooden Piece Weighs 25 N.If It Is Played In Such Way That Its 25 Cm Length And 10 Cm Width Are In Contact With A Surface,Whay Will Be The Pressure Exerted By It On The Surface

Answer 1

Answer:

pressure= force/area

Explanation:

so. if the surface is in contact with the side having 25 cm length and 10 cm Breadth . then,

area => 25cm×10cm

= 250cm²

now, we know that

weight=mg(mass × gravitational acceleration)

and also F(force)=mass× acceleration

so the magnitude of force is given as 25 N or 25 kg m/ s²

as the area in cm² so covert force into kg cm / s²

25 kg 100 cm / s²

= 2500 kg cm /s²

now,

pressure = (2500kg cm/ s²)/(250 cm²)

= 10 kg / cm s²

further convert your ans in the unit which you want to
