Pressure = Force / Area
P = F / A
P = mg / A
From above
m = PA / g
= (100 Pa × 15 × 10^-4 m²) / (10 m/s²)
= 0.015 kg
= 15 g
Mass of block is 15 grams
P = F / A
P = mg / A
From above
m = PA / g
= (100 Pa × 15 × 10^-4 m²) / (10 m/s²)
= 0.015 kg
= 15 g
Mass of block is 15 grams

Answer:
pressure = \frac{force}{area}pressure=
area
force
here, force is applied by the weight of the block..
force = mg , where g - acceleration due to gravity
area = 15 sq-cm = 0.0015 sq-m
pressure = 100 Pa
g = 10 m/sq-sec
so, force = pressure x area
=> mg = 100 x 0.0015 = 0.15
=> m = 0.15 / 10 = 0.015 kg = 15 g ...
