Question

determine the force on the ground by a wooden block .If it has a surface area of 2000 square cm and mass of 20kg.​

Answer 1

Answer:

AS WE KNOW FORCE EXERTED BY GROUND ON WOODEN BLOCK IS EQUAL TO FORCE EXERTED BY WOODEN BLOCK ON GROUND.

FORCE EXERTED BY GROUND BY A WOODEN BLOCK=MASS× ACCELERATION DUE IF GRAVITY

$= 20 \times 10$

$= 20newton$

IF WE WANT TO FIND PRESSURE THEN

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

change 2000cm^2 into m^2

=0.2m^2

PUT VALUE IN FORMULA OF PRESSURE

$= \frac{200}{0.2}$

$= 1000pascle$
