pressure = force / area
p = mg / A
from above ,
m = PA / g
= ( 100 PA × 15 × 10^-4 m² ) / ( 10 m / s² )
= 15 g

Explanation:
Answer
The effect of thrust per unit area is called pressure.
Pressure =100 Pa
Surface area =15cm
2
=
100×100
15m
2
=0.0015m
2
Mass = m
Pressure=
Area
Force
or Force = Pressure × Area
=100×0.0015m
2
=0.15N
F=m×g
Let g=10m/s
2
⇒0.15=m×10m/s
⇒m=
10
0.15
=0.015kg
