Hot air balloons don't have pre-planned landing spots due to the fact they travel where the wind takes them. Instead, our pilots will look for a suitable open space and bring their balloon to land in a safe and controlled manner, fully compliant with aviation law.
Explanation:
We know, Weight = Mass * Gravity
Here, Mass = 20 Kg
Gravity = 10 m/s² [Approximate value ]
Substitute their values,
w = 20 * 10
w = 200 N
In short, Your Answer would be Option C
Hope this helps!
