Question

The tip of a drawing pin has an area of 0.01 mm?. Find the pressure exerted by it if a force of 20 N is applied by it.


​

Answer 1

P=F÷A

P=20÷0.001/1000

=20000000Pascal

Answer 2

Answer:

Pressure will be 2000 P

Explanation:

$p = \frac{f}{a}$

$p = \: \frac{20}{0.01}$

$p = \frac{20}{1} \times 100$

$p = 2000p$
