Question

If a force of 300N is acting on an area of 40cm square then calculate the pressure in i) Pascal ii) dyne​

Answer 1

Answer:

Explanation:

Force = 300N

Area = 40cm = 0.4 m

Pressure = 300N / 0.4

= 750Pa

= 7.5 dyne

Answer 2

Answer:

i) 75000 Pa

ii) 7.5 × 10^9 dyne

Explanation:

Force = 300 N

Area = 40 cm² = 0.004 m²

Pressure = Force / Area = (300/0.004) Pa = 75000 Pascal

1 Pascal = 100000 dyne

75000 Pa = 75000 × 100000 dyne = 7500000000 dyne or 7.5 × 10^9 dyne
