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

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 ...
