1] FORCE = 100 dynes = 0.001 N
AREA = 0.02 cm²
$= \: 2 \times {10}^{ - 6} {m}^{2}$
PRESSURE = FORCE / AREA

$= \frac{0.001}{2 \times {10}^{ - 6} } pascal$
= 500 Pascal [Answer.]



2] Pressure = 50,000 Pa.
Area = 0.125 cm²
$= 1.25 \times {10}^{ - 5} {m}^{2}$
FORCE = PRESSURE × AREA

$= \frac{50000}{ {1.25 \times 10}^{ - 5} }$
= 0.625 N [Answer.]


3] FORCE = 5,00,000 N.
PRESSURE = 25,00,000 Pa.
AREA = FORCE / PRESSURE
= (5,00,000/25,00,000) m²
= 0.2 m²


4] AREA = 1.5m²
PRESSURE =
${1.013 \times 10}^{5} pascal$

FORCE = PRESSURE × AREA

$= 1.5 \times 1.013 \times {10}^{ 5}$
$= \: 1.52 \times {10}^{5} newton$
