Answer:
F = 45 KN = 45000 N
Explanation:
Considering the downward direction as the positive direction:
where,
P = Resultant Pressure = ?
P₁ = Atmospheric Pressure = 100 KPa
P₂ = Pressure inside the can = 70000 Pa = 70 KPa
Therefore,
Now the resultant force will be given as:
where,
F = resultant force = ?
A = Area of side of can = 1.5 m²
Therefore,
<u>F = 45 KN</u>
Answer:
