Question

A body weighs 20 kg kept on a surface of area of contact 100 cm2 then the pressure exerted by the body on the surface

Answer 1

Answer:19600 pascals

Explanation:

P=F/A

=20kg*9.8ms^-2/0.01m^2

Answer 2

Answer:

196 Pascal

Explanation:

$force = mass \times acceleration \\ force = 20kg \times 9.8m \div {s}^{2}$

$force = 196 \: newton \\ pressure = force \div area$

$pressure = 196 \: newton \div 100cm$

$100 {cm}^{2} = 1 {m}^{2} \\ 196 \: newton \div 1 {m}^{2} = 196pascal$

$196 \: pascal\: is \: the \: answer.$
