Question

Suppose you balance a 2-kg ball on the tip of your finger, which has an area of 1 cm2. Show that the pressure on your finger is 20 N/cm2, or is 200 kPa

@Abhisar

Answer 1

\[Pressure = \frac{ Force }{area}\]

Answer 2

(2*9.8)/1 =20N/cm2

Answer 3

got it ?

Answer 4

we always multiply by9.8?

Answer 5

yes, sometimes we can take 10 for ease of calculation

Answer 6

i see ok. that makes sense

Answer 7

ready for next one?

Answer 8

actually to convert mass into force we multiply mass by accelaration due to gravity i.e 9.8

Answer 9

ok

Answer 10

it is making much more sense
