Question

Find pressure exerted in the following:a) force of 20 dyens on 15 cm square

Answer 1

Covert dynes into Newton by multiply 1 multiply by 10 to the power - 5

Use pressure = force divided by Area to find pressure.

Hope you get your answer.

Answer 2

Hi friend,

First we need to convert dyne to N as unit of force is newton.

F= 20×10^-5

A= 15cm²
A= 15×10^4m²

Pressure = force/area

Pressure= 20×10^-5/15×10^4

Pressure = 1.33×10^-9 pascal.

Hope this helped you a little!!!
